- You've always seen the rebuild kits for these brake cylinders, and I've always wondered how difficult would it be to just rebuild it and save the money. Or maybe you're rebuilding an old classic car and it's just difficult to find a cylinder to put on the car. It's a lot easier to find the brake cylinder rebuild kits. For whatever reason you're interested in rebuilding the brake cylinder this video shows how to do it without expensive tools. Hope you enjoy the video.

This is some Bob Ross level narration! Great vid!
Mr Rogers rebuilds brake cylinders! 😊 Loved this
I like that he is not gloved up like an operating room doctor. Down and dirty and so practical.
Nice. When taking off the old seals, I used a small screwdriver to push the seal out (from the back of the piston, this was from a Toyota) and then used wire cutters to snip the seal as to avoid scraping the outer diameter of the piston. For install, I tried using a spark plug wrench, a 1/2 inch extension, sockets, all types of stuff. What I found out is that you can stretch the rubber out a bit running it up a 1/2 inch with some brake lube (or fluid), use a little bit of the same lubricant on the inner diameter of the seal, and then just pull it on by hand. It wasn't very easy, but it works and does not cause any type of harsh contact to the piston like a tool might. I think the other commenter is right about getting some heat on the seal, I left mine in the sun while working on them and probably happened inadvertently heated them with my hands and friction. I think your method is overall easier and faster though, and the only improvement I would make would be to size the cone just large enough to slide over the piston and then just pull straight down without the use of a pencil. Also, for any readers, be sure you know which way the seal goes on before installing. Use the old pistons as an example, or if you're unsure, get an OEM diagram (from which I found on an OEM parts site). Hope this helps someone.
Always satisfying to repair something if possible rather than just replace. One thing I learned is in case of emergency repair if there is no new rubber rings available you could just put several lines of thread around this grooves and put old rubber rings back. That will push old rubber ring out and will work good enough. That's bush repair until available to do proper replacement with new rebuild kit as on video.
Thank you. Very innovative. In the late '60s I tried to rebuild the rear wheel brake cylinders on my 1965 MGB roadster; afterwards they leaked like the proverbial sieve. Let's see, now I have to remember to save an empty caulk tube....
Use a hairdryer to pre-warm the rubber immediately before installing, to make it flex easily onto the piston.
good idea
Good video. You installed the piston seals on backwards though which will also cause them to leak.
I saw that
And you ahve to be carefull with the rought surfaces when honing cause othjerwise seals will not last too muchj
This guy got me putting up the seals wrong 😩🤦🏽♂️🤦🏽♂️
Fantastic magic trick!!! I love it. Thank you.
Was debating on doing this for my truck, think I will try it today. The calm and concise narration juxtaposed with the anxiety-inducing shaky hands gave me a good laugh. 😂 Thanks for sharing!
how did it go?
Good tips, one thing I would add is that you can and should use some brake fluid to lube the new rubber pieces when you are installing them. It makes it much easier
Good tip
Thx
Great DIY! Thanks.
Brilliant, many thanks
nice video and great tutorial thx for posting
Nice Job.
Very Good Job.!!!!!
excellent job
Not just thumbs up i would kiss you xD today i have noticed that one of my rear wheel cylinder is leaking oil so I checked up and the price was about 25usd thanks to your video i have now know that it can be fixed.thank you so much
The rear cylinders for my old z car are 56 bucks a piece. Thanks for the tips.
YOU ARE THE BEST,,,,,,,,,, Thank you so so muchhhhhh
thanks nice video You can heat it also with lpg torch no red heat a little heat to
open the brake line
great idea bro.
Very nice bro 😀
Thank you
good info
Fantastic video thk u
شكرا كثيرا ,, انت رائع وشرحك رائع
Bravo!
appreciate the video, but I have a couple of questions for you if you have a moment. On the rehoning what grit or grits did you use and I am assuming your just looking for the lightest sanding you can do to have a smooth bore. Second question, when I squeeze my brakes I only see the piston side move maybe 1/8 inch the adjuster side does not move. So it looks to me like I am only using 1/2 of each side of my pads. My 3rd question here is I have oil in my dust cover seal, this means mine are leaking and need redone?
I like this video
Cylinders on my oxford mo are over 200aud! Thanks for the great video
for my car is 17 euros,, each one doesnt worthrebuild
@anteneupitra makes sense. The Oxford is 1952, not much support in Australia, so most of the parts come from the uk, with big shipping bills....
Good tip. Here is one for you. Make sure that the brake bleeder comes OUT BEFORE taking it off your car. Because I had them to brake off, this can you some time if this happens.
Does the outer ring tend to have a small hole?
my 78 Olds Delta 88 has a cup style rubber seal that is so tight (two different seal kits) you can depress the spring completely and it doesn't move/ what to do?
very good slow video
Unless it is a classic car & the wheel cylinders are obsolete,the labour costs exceed the cost of buying & installing new wheel cylinders.
I've got nothing against the do it yourselfer as I'm one of them myself although I am a trades qualified electrical fitter/mechanic who used to repair power tools (i.e. jack hammers,etc) which needed rekitting.
I have recently rekitted the brake master cylinder on my dads car because him & my brother the reservoir grommets were leaking.
All it was ,was the lid seal which leaked fluid but I rekitted it because I knew there was something wrong with the master cylinder.
There were no internal leaks rather a stuck proportional valve which wasn't allowing enough fluid to reach the front brakes,the brake pedal also felt spongy.
The brakes really stop by the car well now.
I've done this before on different cars,I need to overhaul the front right brake caliper piston because the pads grab & the last set wore unevenly on that caliper which usually indicates that it has a stuck piston.
So,for $19.99 AUD , I can have a rebuilt caliper, I rebuilt them 8 years ago but I replaced the whole left hand front caliper with a new one as the guide pin bores wore out.
I chased up another bracket for the right hand side but the piston is stuck again, maybe some dust got pushed into the piston & cylinder !!!!
GREAT VID!!! This video helps in many ways because not only did I learn how to rebuild if I couldn't find the part, but I now also have a deeper understanding of the mechanics on how this thing actually works on the drums. If someone has a bad cylinder I know in detail why. If there are negative comments on what you are doing here, then that can only mean that someone is one short of a bolt or could use a brain tune-up, and they would need a different TH-cam channel for that. Keep up the good work man!
good ideas, but I would lube that tapered tube with brake fluid - wouldn't that help?
Thank you for making this video. I wish you would have showed the complete disassemble and reassemble, even if you did so while fast forwarding and using captions (for the novice mechanics).
Nonetheless, I think it will be enough :)
Where can I get the rebuilt kit ????
you put the inner seal backwards the open part of the umbrella faces the pressure so it will expand under pressure and seal
The tricky bit is unscrewing the metal brake pipe, if the nut is rusted to the pipe , the pipe can cork screw . ( cars with fixed rear axle or 2 cylinders on each wheel) . Instead you can "hone" the cylinder with it on the car.
It seems wheel cylinders , new or rebuild only last a 2 - 4 years.
in past last much more time,, buy good quality rubber..
My 1936 Buick, Series 40, can find cylinders so going to rebuild old ones. 1949 Buick is a lot easier to find brake cylinders. Thanks!
Fusick automotive parts, Kanter, bob's automobilia
Only thing I'd skip is the half inch extension as leverage. One nick or bump in the cylinder walls would cause leaks all over again.
درود بر شما متشکرم اقا
I use teflon tape on my bleeder screw threads, just the threads.
I have only just come across this video and I would advise anybody to take great care in following Error Code Guy’s advice on several points
To start with the first thing they teach you at “brake school” is to have absolute cleanliness when dealing with brake parts, so ECG’s oily hands are a definite no-no
Secondly when removing old seals with a screwdriver do not point the screwdriver towards your hand as ECG does at 3:25. The screwdriver could slip out of control and cut your hand severely as you are using quite some force to get under the old seal.
As already mentioned old engine oil is indeed carcinogenic so use vinyl or latex gloves. It is also much easier to get your hands clean afterwards.
Honing the inside of the cylinder can be done with sandpaper but use fine grade only as any grooves left inside will quickly ruin your new seals. Use clean brake fluid as a lube all the time and definitely no oil of any sort, since any contact with oil will swell the seals and render them useless - again absolute cleanliness is necessary and oily hands are definitely not allowed here
Fitting the rubber seal the wrong way round is an absolute beginners fault at 4:39 and on, and I would therefore consider this video unfit to help a novice. Chances are you will only find out about this when everything is put together and you are wondering where all the brake fluid came from . . .
My advice when using educational videos is to watch as many as you can on any one subject before trying the job yourself. That way you will quickly learn to separate the cowboys from the professionals.
Eddie Linssen Where is your video showing this done the correct way????
WTF your link takes me Energizer batteries!
You can poke open your finger while removing rubber seal from piston..Use thick rubber gloves insted of bare left hand fingers.
My brake cylinders looks like they’ve been on the bottom of the ocean for 20 years. I think i need new ones.
Some of mine are there
genius
Use only A PENCIL. Because only A PENCIL (sharpened of course) will add the right combination of graphite, wood splinters, and paint flakes to the cylinder for a proper seal as per OEM spec.
your wheel cups are in the wrong direction
also hes allowing petroleum based products on it
@@MrShaun1578 petroleum products rot rubber
Use RUBBER GREASE on water based brake fluid systems.Make sure cups are fitted on cylinders THE RIGHT WAY ROUND..
That magic trick is awesome! Now let's all NOT wait 10 years before changing brake fluid again!
the rubber cup seals are facing the wrong direction.
Probably should use fine sandpaper (220 or higher) at least
I dig the sloppiness though
needless to say but some times we got to rebuild parts because some parts are hard to come by.🙏
Brain it shape kinda like along square
Fine, well and good, but ain't got 2,3 days to soak.
i repair brake cylinders full time. that has got to be the most awkward of doing a 2 second job. (seals are on backwards)
Why do some “mechanics” have the shakiest and most unsteady grips and hand movements?
Exposure to hardcore chemicals.
@@ipwee And that's why gloves are handy
I shake due to overdoing the coffee. Every day. It's a tradition.
You blew it!!!!
Ahh....Never never never use
sand paper! Always always always
buy and use a brake cylinder hone
tool . My goodness.
Looks like he fitted the rubbers the wrong way round! lol
why am i looking to rebuild a cylinder. because not even a torch and hammer could take the old one off
watch this video and learn how to 1. save money 2. do it you're self
You didnt explain how to remove the old seals.
Does it matter? You aren't using them again, cut them off.
this is the most bush league repair i’ve ever seen
Wheel cylinder for electric cars like ezgo Industrials have rubber KIT for $27, rubber and piston for $74, and the whole cylinder (torque spider) for $200!
So yes, rebuilding one for $27 dollars is better, can you believe the rubber alone is $27! I shopped around and the prices on carts parts are insane.
you put the washer in the wrong direction
Jajqjajajaj como tiembla para meter el jebe y encima lo mete al reves
Just buy the whole cilinder
New one cost less than $10. Are you not sure it's a waste of time?
Depends on the car, for my 1931 Morris was £70 each, the kit was £7.
Toss them and buy new wheel cylinder,most are $20.00 and less
On rock auto most are 5$ brand new. Seriously 5$ most vehicles I’ve done many
Rock Auto is not an online auto parts store with no warehouses.They buy from the competition getting parts from their warehouses
All this work just to save 24$?? 😨 Oh, man, this means your time doesn't worth anything... 😑
Maybe you can't but them anymore?
dawg clean yo nails
Just buy a new one... dont waste your time
$350 each vs $33.50 for a seal kit, I know what I’m wasting my time on.
Rebuild because its made in china.
only watched a minute and have given a thumbs down for being an idiot and not wearing gloves !! Don't you know that automotive fluids, such as brake fluid (especially) and motor oil (especially dirty oil) have a great many nasty things in them? The skin is highly absorbent and many things will pass into the blood eventually. No wonder so many people get cancer these days and then wonder why. There are so many great form fitting work gloves on the market these days, nitrile and normal types, even food handling gloves are good and don't get in the way of detail work. So there's no excuse. Plus the hands stay pink and clean with no filth in the pores and creases and no more rough skin. It's 2018 and it's a no brainer .
