As a 20+year Mechanical Engineer who designs and builds precision, robotic automated industrial machining systems that have to run 24/7 for years on end making OEM automotive parts, I'm more impressed with Eric's professionalism, work ethic and attention to detail with every video I watch. He does it the correct way, doesn't cut corners and explains it very well. I wouldn't hesitate to have him work on one of my vehicles. Technicians like Eric are *very* difficult to find, whether it be automotive technical work or industrial technical work. They are out there, but they are rare.
Well thank you sir but I just consider myself a mechanic. Technicians are educated professions IMO
Different school. Eric's is a master as defined by the french apprenticeship system. I was an HVAC mechanic for 40 years. I had two tool boxes. One was physical and one was mental. Every time you solve a new problem you use tools from both tool boxes. If you learn something you add another tool to the mental tool box. Eric is a young man those mental tool box in overflowing.
There are many different types of education in this world. I'll take your type of education over book-schooling most any day for technical work. Self-taught is very valuable when taken seriously and you obviously do take it seriously or you wouldn't be as crafted as you are. It is obvious that when you run into an issue that taxes your knowledge, you educate yourself on that subject. That is the most valuable type of learning because it is retained. A lot of book schooling goes in one ear and out the other because there is very little "want to" in the process, most are doing it to get a grade or pass a class and will retain the information just long enough to do just that. When you stumble upon a problem and *really* want to know the answer and you dig and find it yourself, you are much more likely to retain that information for life. That type of learning builds a knowledge base that cannot be replicated in a classroom.

Had to go and find this. My son has run the pads so far that the backing plate has slipped out and the piston blew out. Your quality of video has gone up and you are more relaxed in your dialog now but the information is spot on , even back 9 years ago.
wow back a hundred years ago an ancient video i am doing my legacy pretty easy job but always fun to watch all your tips.
developed some sort of metal rubbing on my subie rear wheel at slow speeds, not while braking. something is got stuck somewhere or another. Came back to watch this as a reference. Man I really think this is Eric O's best video ever. I really wish, I could just go into a shop and say " I Want to the Eric O standard of brake change" and they would know exactly what I want. A local shop I saw was putting on brake pads (on another car) didnt even change the brake hardware, I died inside knowing, " I gotta find another shop" I Guess I gotta stop pissing and moaning and get my own quality floor jack, and do this myself.
This was EXACTLY what I was looking for to change out the pads and rotors on my 2014 WRX as my first brake job ever. The thorough explanation and justification of your instructions and methods are spot on and incredibly helpful especially with respect to New York winters/cars (my pads went in smoothly after a little filling). I'm in Rochester, but if I were further south, I would definitely be giving you my business! Thanks again!
Hi eric
Was speaking to my son the other day and i mentioned that i found your channel on you tube and had been watching all your vids. He tells me he had been watching your channel for years and thats where he gets all his tips/hints and general insights on how to work on his cars ( Like you, nothing phases him and he can fix anything too! ).
Keep up the great vids Eric.
Cheers
Robert from OZ.
Super cool thanks Rob from OZ
Eric
Thanks for your reply. I know your a busy bloke so i wont bug you any more but keep the vid coming. Always keen to see what you have been working on.
cheers.
Rob from OZ
I wish more mechanics were like you Sir. Professional.
. Hey Eric. Thanks so much for this video. I had an intermittent squeaking sound from my brakes for years that I couldn't figure out. Turns out all I had to do was put in new hardware and grease the contact points Like you showing the video. I was Almost ready to buy new rotors , but you saved me a ton of money and aggravation. The noise is finally gone! Appreciate your channel so much. Keep up the good work buddy
Glad it helped!
By far best, most comprehensive video on this subject. I learned a lot. Great Job!
Gotta agree about the attention to detail. I thought I was thorough, but this guy is good! Picked up a few pointers myself so this vid was well worth watching!!
From WNY Here, this video is great! I'd love if you put out more videos on this specific model because I'm trying to learn to work on my own car and your videos make it very easy to follow. Thanks a bunch!
Thanks for watching Joe Georges ! I'll do what I can for ya but running a full time shop here I just film what comes in. What part of WNY do you live in?
I'm from a suburb right outside Buffalo called Williamsville. About to jack the subie up, let's see how it goes.
Oh that's really cool, I just a few hour away in Steuben county. Be careful out there my friend! Shoot me any questions if you have any!
Just took the caliper off and cleaned it. Are there any ways to clamp the boot in without a vicegrip?
A C-clamp or big channel locks?
this is an EXCELLENT video YOU ARE A GREAT INSTRUCTOR! THANK YOU SO MUCH! GOD BLESS!
Eric thank you. This journey I started about what a month ago... maybe two, of working on my car myself has not been easy and holly crap I have already made all the mistakes you warn again... like for example
... I did not know about your channel when I did the first repair job on Suby... she had broken 3 hub bolts while I was on a bridge on the freeway here in Portland OR... at the time I thought I had a flat tire and honestly did not know much at all about working on cars...
My father bought cars from auctions and he and my moms dad would fix em up and flip em... my dad passed when I was 6 and my grandpa passed when I was 28 but he was jahova's whitness and my grandma said I was a evil worldly person cuz i graduated from gateway "christian" academy plus I lived in Memphis TN and they lived in Arizona....
well no one has ever wanted to teach me or even offered to lend me tools to learn. So I enventually just gave up trying to work on cars and became content with my love of just driving them. That is until my hub studs snapped off like 3 or 4 months ago...
I didnt have the money to pay a repair shop or a mobile mechanic.... so what did I do? I jumped on the tube of you where I discovered about a billion videos on cars and suddenly became very confident in my ability to do the job myself. All I needed was some tools so I began to ask around... if I could just find someone willing to lend me their tools... I am a pretty lucky person at least I believe I am and low and behold my cousins husband was kind enough to lend me some of his....
after many videos and boost of confidence I headed out to my car where ... I learned that I now needed to learn how to jack her up because it wasnt as easy as I remembered my old cars being...
so I went back inside and looked up videos about jacking cars up...
then I returned to Suby ready to get started... until I realized that the places the videos had said to use to jack her up did not exist ... the information I had learned does not work for Suby she is not made the same as all the other cars.
so I returned inside to find better mechanics with better videos hopefully ones with cars exactly like mine...
Eventually I found 3 and I finally got Suby up in the air
However that was about it for that day because well... I did not see this video you have here... if I had it might not have taken me 3 days to get one rotor off...
I had the parking brake on... BECAUSE (yes im laughing too) the other videos all tell you when you jack your car up you must put the parking brake on for safety or the car might roll off the jack stands and crush you...........imma let that one marinate.......
ok so after hammering and hammering and hammering i was about to give up when my cousin called and asked if I was done with the tools yet (day 3) she suggested I used some PBlaster...(she did not know my parking brake was on) I ran to the store got me some PBlaster and some WD-40 Penetrate and soaked the entire rotor as much as possible using half of both cans then waited 30 min... returned to Suby where I still... Could not... remove... the freaking rotor... (I did cry) I decided to just try and pull her off real hard with all my strength and it worked! I finally pulled the rotor off ... falling on my rear end at the same time...
I was ?!?shocked?!? to see a DRUM brake on the inside!!! I went ran to the parking brake... released it... ran back around and cussed out loud because the freaking drum brake! well you already know... Then I laugh ran inside and told my boyfriend ... he laughed too cuz he told me to put the parking brake on... we both literally just learned in that moment that well why that was dumb...
so once again i return to the tube of you...for the next steps... Now the rest well it took a little effort to learn but I did notice something pretty neat... PBlaster not only penetrates seized things it also melts rust a bit so I sprayed everything and scrubbed everything with my harbor freight wire brushes... there was so much of what I thought was sand and sludge and just build up everywhere that I couldnt tell what was a bolt and what was not a bolt... by the time I got done there were different colors in the wheel well that had not been there before... like whites and blacks and orange stickers even...
I was sure that the strut and everything was fine because well there was no oil mark or anything like there is on all the videos I saw... but at the same time all the videos had fairly clean wheel wells none looked like mine... I just assumed since the place I kept my horse was on an Island that it must have been sand build up and had to be normal you know... So after I got done cleaning it all off I went ahead got started on removing the hub bolts (ROFL)... or at least I tried to...
I looked and looked and looked for a video that would show me how to do this without hitting them with a hammer or heating them with a torch... both of those options were out... I had already started smashing the end of the first bolt I wacked with a hammer and I did not want to put a torch to my car... (OMG can you imagine if the stuff all over the wheel well was flamible? I mean well is strut grease flamible?) Well any way I decided it would just be best to spay PBlaster all over the studs and leave it to soak over night...
I am a genious cuz the next morning guess what two wacks of the hammer and stud pops right out! Well I go to put the new one in and ... it starts to sit crooked....
So back to the tube of you... (There is a part that does not exist in the world anywhere other than Amazon that you are supposed to put the stud into and then you just like tighten it and it goes in straight every time easily...) Some guy said that I could use lug nuts to keep it straight... some Chick said I could use a ball joint tool to press it in... Do you wanna know what I used? A freaking Hammer because I finally found your videos! Thank GOD!!!
Still I had yet to find this one... So today when I learned that over greasing the caliper pins is a problem and that the problem it will caused is exactly what my car now sounds like and looks like well lets just say I really really wish that I did not live in the city with no driveway and only street parking... because I would make so much more progress if I didnt have to stop at 10pm because the homeless begin to wake up and roam around scaring the crap out of me and stealing my tools... The other day my torque wrench went missing and 3 days later it showed up on top of the Taurus on top of the tree droppings that are an inch thick because the tree just dropped all its helicopter seeds so I know I did not set it there... It was nice that they brought it back though so I cant be mad that I had to take the crappy one I bought an hour earlier back to harbor freight... I thought "oh cool I can have some money to buy some crystal gemstone beads and finally make my friends bracelet I promised before the car broke" then I got to harbor freight and decided it was a good idea to just look around... When the first thing fell out of my very full of tools arms I decided I should check out and leave... I had to pull my cash app card out and pay the now $50 more than the money I got back from the torque wrench... This happens every single time I enter any car store or tool store now... So im not allowed to go in alone... I am also not allowed to go in with just my children because I have learned to convince them its a good idea to get more tools since well they can get toys too and my daughter can get things to decorate her room ....
Now any time I am discouraged I just fast forward your videos to the end... Because I can do it too ;)
P.S. I shared another comment about a week ago... I found a rust remover that turns rust to mud you can wipe right off... it also lasts as a shield for up to a full year in the rust belt ... it is called RUST SHEILD by PBlaster... if you do not get yourself a bottle soon I am sending you one and I wanna see you use it because it is going to make you a ton of money... You can just tell folks to come to your shop and you will prep their cars for winter and they will never ever experience the issue that come with their cars rusting out again... you can even set up times they need to come back and get a touch up or check up to make sure they dont need another coat or something...
I hope you had a good day yesterday and you actually enjoyed the entertainment of my learning experience I hope one day I will be able to share my knowledge of cars with my kids and that if for some reason I am unable to someone else will and they wont have to go threw teaching themselves like I am..
Charles the Humble Mechanic encouraged his viewers to become certified or a apprentice because the car industry needs more mechanics so I am in the process of trying to find one that I can get a grant for or is free...I am a single mom with 3 kids and a horse... who lives in Portland OR and currently has a $2500 rent bill plus everything else just got more expensive... I am kind of glad my cars are broke down cuz gas is stupid now... I just wish I lived out in the country next to my horse cuz not being able to go see her is taxing my mental health... Watching you and your family and learning from you is helping me stay saine so thank you ... Much Love Lanna's Mind

Thanks for posting this. I just did the rear brakes on my 14 Imprenza. This was the first time that I removed the brake caliper bracket.
Just started watching your channel. Really like it. You are a good mechanic. I have a WRX so its nice to give a watch before I have to do anything. Thank goodness its a 2017, so I have a way to go.
Great video When working on ABS brakes I all ways undo the bleed nipple before pushing the pistons back, I have know the seals to turn in the Brake Modulator and you know how expensive that can be. I have a brake tool that I put on the brake pedal that keeps the pressure on the pedal and it follows the pedal to the floor, so when you open the bleeder nipples there is no lost of fluid and the fluid can't return up the system, no bleeding required. I also use it for setting different engine speeds when testing
Wow, great video! Don't know when you started on TH-cam, but you can certainly tell the difference from your latest videos to this one. :)
Eric, I like a carpentry c-clamp and a small piece of plywood to shove the call per back in, nice even force, no chance of marring the surfaces.
+erg0centric Yep great idea!
I just put the old pad in when compressing caliper Pistons.
Where i live the rust is really bad(NW ontario) so I actually go lightly over the area with a cut off wheel on a die grinder to get it to bare metal. Works very well.
+Zach Pascoe Yep good method!
Howdy Eric. Ive been watching yor show from Aus for some time now.
Excellent coverage of all aspects in the workshop n out.
I noticed in this Episode your blasting cabinet.
Can you please do a 5 min segment on your cabinet and all components.
If no time , no worries.
Steve Muller
Hi Eric,
Awesome videos!!! I just did my first brake job today. Well kinda....I helped my brother out change the pads on his Prius. Thanks 4 ur help.
+worldtraveler2500 Hey that counts!
What about knee pads, hearing protection, and respirator? Sorry couldn't resist. LOL! Slow news day over here, working through your older material. All good stuff!
Lol
@@SouthMainAuto simple but effective reply, could i ask what type of rotors are the best for money when replacing them?
Fluid Film is sold at OReilly Auto Parts. It's great for yard tools because it doesn't kill plants.
Awesome video, thank you for taking the time to produce it. I’ll be performing this work on my wife’s Impreza next week.
Great information. You’re organized and have a great teacher attitude. Thanks
My EBC Red pads came with what looked like a small pouch of copper based anti-seize as the grease. I put it on the plastic adhesive shim, and on the rails/pins as instructed, seems to work fine.
Great video! Had everything I needed, especially the parking brake adjustment (haven't done that one yet). Keep these coming, I love saving money by doing my own work!
Glenn Holler Glad it helped :)
I am enjoying Eric videos also. Thank you Eric. I would like to to trow my 2 cents into parking brake adjustment. I have subaru outback and I have run into the trouble when replacing my parking brake shoes.I was looking for solution on TH-cam how to adjust parking brake and found one video. From that time I am always using same trick works every time.
1. You loose brake pads so they not touching rotor.
2. Then you go inside and pull parking brake 3 clicks up.
3 Come back and adjust that screw so the parking brake shoe touch the rotor( and you are not able to spin rotor)
4.Go back inside realise parking brake and check that you can now spins rotor now)
That's it your adjustment it's done
Hope that will someone as it help me
I like that mini car lift.
Something like that would come in handy in a home garage.
Nice tip on cleaning the extended caliper piston boot before retracting it.
They are perfect at home lifts. They are portable too :)
+South Main Auto Repair tell me that you have a link to that lift in your store...
Just did a complete brake job on a buddy's 1990 Honda CRX Si. He installed Hawk branded high-performance pads. I cleaned the caliper brackets and hardware (new pads didn't come with hardware or shims) very well, but still had to grind down the ears on the pads to get them to fit and slide properly. They were almost 2mm taller than what was on there. Some aftermarket parts just don't fit out of the box and these are very expensive pads.
Great videos btw. You do very detailed work. Subscribed!
Audioquest56 Sorry to hear ya had to grind'em down... Thanks for the sub!
Yay finally got time to do my own car (gen2 Impreza)! Interesting; looks like in spite of changing to control arm rear suspension the brakes are essentially the same.. If it ain't broke don't fix it! Thanks for letting this rookie mechanic answer to his caution (with good reason..) once again ;)
Very thorough video, nicely done and an excellent, thorough job doing the brakes. Thank you. Wish I had a sandblasting cabinet :)
Cleanliness is what makes for a great brake job! Ya they'll get dirty, but they'll work smoothly!
Is this the first SMA brake video?!?!
And he’s already in the brake clean!!!
Nice video...very helpful. My subaru has about 30K miles and I was thinking about just changing the pads and not the rotors. Do you recommend always changing the rotors every time the pads are changed?
Marisa Stancroff Inspect the rotors, but for sure not change every time.
Check for overall thickness, any deep gauges (ie from rocks stuck in the pads), warping, etc.
I usually get 100k miles/2-3 pad changes out of the rotors on my Impreza.
Thank you very much for sharing your knowledge and experience. I appreciate it.
Did ever have issue with brake lubricant Permatex purple extreme ? I heard they may swell the sliding pin rubber, especially in Subaru.
Man I love all the details you give. YOUR THE MAN. THANKS
one of the better videos of this sort I've seen. thank you, sir
I agree he does every repair the way it should be done. Every other mechanic video I have seen do not talk about the parking brake adjustment except Eric O...that i remember.
This guy knows his stuff!
Thank you for your very clear and informative video. Off now to do my forester. Regards from N. Ireland .
Thanks for this video! Doing my first complete brake job on my 2010 impreza soon. Do you think a C-clamp and an old brake pad or piece of wood would work just as good to depress the piston? Thanks!
yes, I've only used a c-clamp and the old brake pad for the 25 plus years
Frist time I’ve seen a combination disc and drum brake. Was that Hotel California playing in the background, btw?
Finn Schøyen The drum is the emergency brake
Very thorough video, thank you. It was most helpful and again I appreciate your attention to detail.
Thx, Ed
WHAT! No respirator to protect you from the hazardous brake dust?!
lol
As a DIY guy, I always look for thorough videos from a down to Earth reality. Thank you for your replacement video.
Now go visit NASA and get yourself one of those space suits with a helmet to protect yourself from all the hazardous chemicals and from bumping your head in the wheel well, lol.
:)
love it have a impreza 2000 you did a great job I am going to try this myself.
The rust inhibitor you speak of that is generally used on brake parts is called Cosmoline.
Isn't that the same rust inhibitor that the US military uses to store firearms?
best video I've ever seen on brakes
Hey, I just did that on my 2015 Forester after a caliper failed at 36,000 miles. I guess I can do it!
Until you did this job I never realized there were companies that had drum brakes for a parking brake and disk brakes for stopping. When I bought a 70 Chevelle the reason it had drum brakes on super sport was because of the parking brake. My next door neighbor used c-clamps to pull the pads in on his daughters Chevy smashing the heck out of the pads to get it to fit not realizing you just turn the puck to adjust it in and out. When he got through she only had front brakes.
best brake job video i've see. subscribed and bookmarked... thanks
A great video. A big help - thank you. Love your videos .
Eric, excellent video as usual but, you gotta get a better bench grinder! You were hardly pushing and it was almost stalling out.
Look for an older Craftsman block grinder.
+Bruce L. Yeah but you appreciate that feature when it sucks your finger in!
Great video,Thanks! Now to do my Brakes on my Subaru!
Great videos thanks for sharing your expertise. Recently picked up a 2003 Subaru Outback and replaced all the fluids and all pads and rotors. By the way, what kind of lift do you have the car on and where can I get one?
First brake cleaner and fluid film combo on a SMO video?!
great info what is the name of the lub that you used to prevent the brakes from squeezing
Eric those rears have at least 5-6 feet left in them.
Great videos. I'm working my way through from the beginning.
I'm a fan and big user of brake clean also. But I'm a cheap skate.
Have you tried a non-aerosol sprayer like Sure Shot or Titan Tools Spray Shot and bulk brake cleaner?
I don't know the break-even point, but I don't run out in the middle of a job like I use to.
Thanks for the many great videos. Mike
Boy the customer got his money worth out of those pads
+Eric Corse Sure did
I hung my head in shame when you said you should never Force brake pads
eric thanks for another great video, you da man
+nigel kendall Thanks!
Nice explanation, beautiful work.
how in the heck was he able to stop? maybe a flintstone feet out the door. Standard transmission is how he stopped lower gear. Eric you the man
+Gary Johnson Very carefully :)
Hopefully, it was just the rear pads that were so worn. The fronts do most of the stopping.
thank you Eric Another Awesome video
Thanks just did the disc brakes on the Rear of my 08 Subaru Impreza WRX , do you have a video for the drum brakes on the rear they need replaced to lol
Neboro Haven't done one on the drums.... yet
Excellent job thanks for the video and info
Thank you. I've got a '97 with 270K and just about to order complete kit. Rock Auto have power stop kits with OE rotors, ceramic pads and the hardware. How does a person know what is a good set? thanks again
Extreme! Great Video.
Second time watching 6/20/2020 great job like always A+
Brake Clean yeah, I use them on almost everything!
THE BEST GUY EVER GREAT JOB
I wonder if this video got demonetized for having Hotel California playing in the background?
thanks for the demo
What brake clean do you use? Do you buy it in bulk? I also love to use a lot of brake clean but find I end up spending a lot on it. Is there any secret cheap brake clean I'm missing. I love brake clean (and its smell!)
Eric are you not concerned with getting blasting media in your slide pin sockets or do you plug them before blasting ? Or hold them upside down and blast a whole can of brake cleaner into em (one can per socket ) to flush out media ?
Replaced brakes 16,000 miles ago with the Wearever Gold brake pads and Platinum rotors. Starting to get brake squeal after driving for about 5 minutes, hopefully the squeal is just from a lack of brake lubricant on metal to metal parts. The squeal is also intermittent, so I am going to pull the wheels tomorrow and check the pads. If needed to replace, is the Platinum option worth the extra money compared to the Gold? I would have thought i should have gotten more than 16k out of the Gold pads if they are bad.
Fluid film product.....you buy that locally or online?....i live just south of woodhull over the border in PA...dont think ive seen it in my local NAPA store....how about the castle products you use also?
+ketcamaro Our Napa and Advance both have it here
what is your favorite rolling chair mine really sucks
Nice video, and great music!
excellent job.
So as I was trying to remove my brake pad brackets.... The bracket bolt completely snapped off. Any advice on how to remove it? If I have to purchase new brackets, I'm totally fine with that.
Where does the squealer go? Inside brake pad? Is it positioned towards the front or rear of the caliper?
i am not able to push the cylinder piston fully back until the gap in the cylinder can fit my new brake pads and rotors. i used c-clamps.
the cylinder looks corroded under the rubber hose. whats the fastest and easiest way to fix it? just replacing the piston by new ones (including the rubber hose) and derust the caliper or to get a new (or refurbished) caliper? (or any other hint, without replacing a part)?
Didnt know I should be greasing underneath the metal clips... thought you were supposed to grease on the clips, where the pads sit. Damn..
What are the torque requirements for the caliper and caliper bracket screws for the front and rear?
What is your opinion if I stay with Subaru OE parts is there a massive difference in terms of cost?
Hey so I have a 2014 Subaru wrx and want to try doing all rotors and pads myself, it looks easy. But I have a question, my car is manual transmission, do I need to do anything with the parking brake at all? I feel like if I don't need to touch it why mess with it?
I would just do an inspection, as Eric shows here.
Also, it's a good time to check the actuator and cable, just to make sure they are good working order.
Do you know if this is the same as the 2013 subaru impreza rear breaks look very close to the same just want to use this video for a work along helper video????
HA yeah like that brake cleaner smell? Breathe in deep! Thanks for the great tutorial
you are the best
nice job
Is there an electric version for that sweet air hammer ??
I dont have access to a sandblasting cabinet. Would a brass rotary brush attached to a dremel work?
TGsrao1989 Actually a brush tends to just "polish" the rust. Best to use a file or something like that to remove the rust if it is present.
TGsrao1989 I
Was your torque wrench broken?
squarewrangler Why?
Extreme, now means standard quality of 30 years ago. xD
Right @Venturi Life
What are your thoughts on putting Loctite on caliper bracket bolts?
Bo Jangles Totally fine IMO
South Main Auto Repair Thank you for your reply. I take it that it's not completely necessary unless the vehicle is used for off-roading or racing, correct?
Can't really say. Around here everything rusts in place lol. Some say it actually keeps the rust out of the threads?! I imagine if you do it by the book it more than likely calls for it...
South Main Auto Repair Everything here in MN rusts in place as well. Good info. Thank you :)
If the factory put it on, put it on. If they didn't, don't. When torqued properly, you do not need thread locker on any bolt unless the factory used/recommends it. That's kinda the point of torque.
Hahahaha...well, I am guilty of grinding of pads (rear). Next time I do my brakes, I'll take my calliper brackets to somewhere where I can get them cleaned up.
Therw you go :) Good idea !
Thank you
eric O do you sleep with brake clean under your pillow?
Isnt bad to push the fluid back up through the system? When i press the piston back in, i open the bleeder and push the old fluid out. Then top off system.
Anthony Sbarbaro It's on a car by car basis. Some ABS systems will not take the back pressure, while others are fine with it.
wow look how far that piston is extended!
Hey Eric, I've got a weird brake problem that I can't figure out.
I'm losing brake pressure over time if I hold the brakes. I wasn't losing any brake fluid at all, so I assumed all the lines and hoses were good. Replaced both rear wheel cylinders, a new master cylinder, and bled all the brakes. Drove it about a mile and still have a sinking pedal that eventually hits the floor. Still maintaining the same fluid level.
I bench bled the master too, so I don't understand what could be the problem now. Any ideas?
Hi, Just read your post; I suggest you change the brake hose lines. Overtime the rubber loses its resistance to expansion thus making your pedal soft and long travel before brakes engages or lose pressure in the lines.
Mr. Zerep Thanks for the reply. I got my problem all figured out about a day after I posted that. I put on new brake hoses up front and the brakes work better than ever before. 250k on the original brake hoses just wore them out I guess.
Also: Because modern brakes use a booster that is connected to engine vacuum, check that hose from time to time.
What will happen is your brake pedal will get stiff -- so stiff that it feels like it won't push down at all. What happens is that the booster hose gets a hole/leak and won't "assist" the brake MC the way it's supposed to.
