Just did mine 1 month ago ....HUGE DIFFERENCE!! feels good from the get go but gets even stiffer after a few days of driving .....side note that line adapter can give you issues when you purchase the line adapter look inside of it the first one i got the threads did not go all the way down so i could not get a good seal went back to the store looked at the last one they had just like i suspected that one threads went all the way down swapped them installed it boom no leak everything is GRAVY!!😎
Yes I agree huge difference nice side note I have had a few guys have the same issue thanks for watching bro 😎
U got a part number?
Thank you! Just did this on my 1999 Tahoe. Night and Day difference! Your instructions were dead on!
Thanks bro glad I could help
I did this mod last week and WHAT A DIFFERENCE!!!! WOW!!!!
Yes it is everyone always comments do it work 😂 thank you for watching bro 👊🏼
I did it, I highly recommend getting thread sealant. Use a lot of it, on the fitting and one the oe line
I’ve done this upgrade multiple times and I have never had to use any sealant and only had a leak 1 time but it was a damaged fitting thanks for watching I appreciate it
Per usual, excellent detail and explanation. I have a 95, and yes, brakes are a little mushy. Time to add this to the upgrade list 😂. Thank you for providing the links to the products used in this video.
Thank you for the support bro and thank you for still watching my videos I appreciate it 💯
@@LowLifeYonkes You’re welcome. Question, bench bleeding, what exactly is that and what do you look for when doing the bench bleed? Thank you.
Bench bleeding is when you bleed all the air out of the master cylinder by using a big screw driver and pushing the back of the master cylinder in and out to get all the air out .... u can do it on the truck it’s easier just how I did it
Your looking for no more air bubbles in the brake fluid
@@LowLifeYonkes Thank you for responding!
I had to stop the video just to say I'm so thankful I found your page!! Perfect content bro!!
Thank you for watching and the support bro 👊🏼
@@LowLifeYonkes @ crees que le kede el master ala 84 square body???
Thank you bro your video helpful compared to somebody else's say their performance they didn't show us part numbers or even show us anything they showed us how to (bench bleed) a master cylinder on a truck not to mention I had not even known what that new body style was technically because OBS well what's been 20 years
Your welcome bro .... I think I know what video your talking about lol .... thank you for watching I appreciate it 👊🏼
Love the video my kit came in yesterday I can’t wait to put in on.
Yea bro it works great for me ... thanks for watching!
Its a lot harder to do on the TBI obs but still possible i just did it to mine you got to really bend those lines with some pliers just be careful and smart how you bend them
Yes I agree I have done both styles and the 88-94 is harder to bend thanks for watching bro 👍🏼
Thanks for the info it was not a plug and I play for me I have a 1989 c1500 and the abs is different and the lines are more forward than your i bent the lines and work way better thanks for the Info the rear one is so hard to bend on the older trucks compared to yours the line is about 2 inches long
Yea bro I have had a few guys tell me the older trucks brake lines are harder to bend to the new location thanks for watching
Just another awesome video from the best source for cool OBS stuff!
Thank you for the kind words brother I appreciate that 👊🏼
Definitely worth it just take your time bleed it well and enjoy
Yes that is key
Great vid, one of the first upgrades I’ll be doing to my OBS
Thanks bro and thanks for watching!
what is OBS ?? Mine is a 1991silverado

In Australia 93 GMC 1500 2x4, brakes are all new and deadly,, i am surprised they wernt recalled from new. this upgrade can help i think.
Yea these trucks have bad brakes from factory this is like night and day difference for me thanks for watching
Just finished my 95 and the results are insanely better. I also did the rear disc brake upgrade as well.
I’m glad it worked out for you and yes I agree night and day difference
My brakes still are spongy after NBS master cylinder and rear disc brake conversion. What could the problem be
@@VON-92 did u bleed all the brake lines including the abs unit
@@LowLifeYonkes honestly I don't know a shop did them so I think I'm going to bleed them once I get home
@@VON-92 I would start there bro
Quick tip: after bleeding the m/c, replace the cap. It will prevent your fluid from leaking out while mounting your lines. Just sayin'.
Thank you for the comment and thanks for watching I appreciate it
@@LowLifeYonkesbro we’re have you been miss the videos

Yea it works bro get it done
master cylinder upgrade make a big difference .
Yes sir it did for me !!!
Great video, i like how you explain and show everything you do...gonna do this..Aloha
Thank you bro 👊🏼
Awesome video big help, so is that the only way you need to bleed the brakes after changing the Master Cylinder. Thanks
I did a bench bleed on the master and it bolted on and I dove it but I did bleed all the brakes a week later with help … thanks for watching I appreciate it
Nice job dude! Thanx.
Thank you for watching 👍🏼
I didn't realize it was that easy Haha. OBS is looking good in the background!
Yes it is bro .... and thanks bro 👊🏼
@@LowLifeYonkes What drop is yours? I forgot lol
6 front 8 rear
@@LowLifeYonkes Meant to ask before...on my dad's truck the brake pedal sticks to the floor and he has to keep pulling it up manually. Do you know what causes that? It's not just spongy, it sticks down.
@@Blitz0065 do you have brakes when it sticks down???
Good videos. Giving me ideas for the 99 burb I've got
Nice thanks for watching
Thanks for the video. I just swapped out mine. For some reason my factory line won’t bottom out to the adapter. Any thoughts or suggestions?
Thanks in advance
Yes double check ur adapter fitting look in side and make sure the threads go all the way down I have more than a few guys ask this same question and the answer is get another fitting same part # but look inside and make sure the threads go all the way down
Ty! I tried your merch link but I think it’s down. Got some stickers?
@@TXPRODUCT thank you for the support yea I had to stop the merch store but I’m glad I was able to give out so many stickers thank you again for watching
Thanks man gonna try this on my 99 Tahoe
Thanks for watching 👍🏼
I Noticed truck in video had 4 wheel ABS. ??? What year was it??? My 91' had Rear ABS only, till removed. The SHORT, Tall Master cylinder......worked, BUT...... NO POWER Brakes any more.
My truck is a 98 but I have done this to older trucks as well
I just completed this mod as well and I no longer have power brakes. Much less peddle travel and a lot firmer but I use the truck to tow a boat and really don’t want to be with out power brakes so I will rebuild and reinstall the original master cylinder. I did bypass the non functioning rear ABS so hoping that will help a little.
I’ve been trying to get a new master cylinder but I’m not sure if it’s vacuum or hydraulic. Is there a difference and Is it the same thing if I just go with a nbs one ? 98 ext cab 2 wd.
Yea there is a big difference it won’t work if it has hydro boost it’s only for vacuum boost
I really want to do this, only question is why did you only need the one fitting/adapter ? Obviously it lined up just fine but I’m curious why. Otherwise this has been on of the best made tutorial videos I’ve seen on TH-cam .
Thank you for the comment and yes I just need the 1 fitting the back 1 is the same thread size you will need to bend the lines back just a lil bit so they can line up to the new master cylinder and that’s it thanks again for watching
Did anyone one of y’all experience a small leak at the adapter ? Everything is tight and still tends to leak a little bit. Nothing was cross threaded incase y’all wondering.
Some of the adapter fittings have a defect u have to look inside the fitting the threads should go all the way down the only reason I know cause a few guys have had this issue and there fittings are the problem same part # but 1 the threads go all the way down and the other 1 the threads stop that’s the defect 1
@@LowLifeYonkes thanks,will get a replacement adapter 👍🏼
@@estebanrodriguez4097 i’m having the same issue just did the swap a few days ago. gonna buy a new adapter and new nuts for both line fittings . did u fix the issue??
Did you have to bleed all the brakes after bench bleeding the mc?
Thanks for showing the obs crowd a great brake upgrade. No adjustments had to be made to the master cylinder pushrod?
Thank you for watching ….. and no adjustment to the pushrod plug and play

Great upgrade for the truck, keep it up 👌🏼
Thank you bro will do 👍🏼
I hace a 2000 tahoe limited . I want to install Wilwood brand . You know if I can get a complete kit ? Thanks
Yes u can get the wilwood for it my boy Chris with the turbo LS OBS has 1 on his he just called and ordered it threw wilwood he also got the proportioning valve with it as well
Gracias OG 🙏🏼
👍🏼
I installed new brake lines metal and rubber on my 94
Along with a new booster and a new obs master cylinder......
Rerouted my lines to delete the dump valves also!!!!!!!!
I'm still no pedal/spongy
Brakes are still no pedal... Will this fix the issue?
Seems like u have replaced everything I don’t know if this will fix ur issue
@@LowLifeYonkes if this does fix it I'll comment back if you are interested, I get the NBS master cylinder tomorrow. I'm starting to think I may need to replace my calipers even though they are working.
They might be weak, but I don't see how.
@@dusterdriven let me know if it does work
@@LowLifeYonkes ok after more digging, my issue is rear brakes, to be more specific... The drums. All this master cylinder does is give more feel to the pedal the under lying issue everyone is over looking is the drums themselves. 20+ year old trucks.... It's time to replace the thin worn drums =( expensive but much much needed.
So to recap the more beneficial "upgrades" I've done.
Abs deletion- do it, the dump valves and abs computers are expensive and the valves cause problems anyways.
Nbs master cylinder (questionable)
Obs is a little looser, yes; but if it's spongy.... You have other issues.
On a side note, it feels more modern with an NBS with more feel in the pedal. I like the shorter pedal distance to brake.
It's sorta like driving a tiny car with a super touchy pedal.
Older guys may not like a touchy brake pedal though, it's more of a younger guy troup.
For anyone following along I can explain the feel using a muscle car.
Obs feels like a manual brake in a Plymouth duster.
Nbs is like you added a booster with a wilwood prop valve.
I've learned allot on my expectation to solving my sponge....
Here's another one guys forgot to do....
GREASE ALL SLIDING PARTS ON YOUR CALIPERS - CLEAN THE SHÍT OUT OF THEM!!!!!
But thank God for this TH-camr recommending an alternative to our crapy obs/S10 master cylinder
@@dusterdriven nice bro good work thank you for the update 👍🏼
The brakes on my 93 OBS are horrible.
I should do this!
Yes you need this 💯%
I need to do this to my truck.
Yes you do bro it makes a huge difference
Great vid and information. Do you know what master cylinder will fit the hydroboost application? I ordered this and break booster and hydrobooser master cylinder are different and im in search for a master for the hydroboost. My breaks are spongy 1995 OBS dually 454.
No bro I’m sorry I don’t know what hydroboost would work I would try the Chevy NBS hydro boost see if that works
@@LowLifeYonkes got it! 2001 chevy Astro Van Duralast MC NM2779 no adapter needed. Hydro boost sys I'll post a vid soon. Thanksv
@@DBIE_music_IE nice bro 👍🏼
What’s up bro. Me again lol. What brake line adapter size did you use to connect the brake line to the proportioning valve. I’m getting rid of my abs unit but I can’t find the correct adapter. Thanks.
I have deleted my abs yet bro so I don’t have an answer for you sorry
So did this truck have the Kelsey Hayes and also, did you have to bleed every wheel?? Mine is a 1995 Suburban with the Kelsey Hays brake module thing or whatever it is
Yes both my OBS trucks have the Kelsey Hayes abs unit witch you have to bleed every wheel and the abs
hi man, how is the pedal feel after the swap? is it too soft? meaning does it bite on the brakes with a little push? would you wish it is a bit more harder? or is it just right? I have a vacuum booster too. this master cylinder you're showing has 1.33" bore size which fits vaccum boosters. just wondering what if I put a 1.45" master cylinder that is usually labeled for hydroboost? the bigger the bore size the harder the pedal feel gets. would you recommend to try it? thx alot for the video!
Thanks for the comment and I feel the pedal firm now with less motion to stop witch is like night and day compared the the stock master and I am upgrading the brakes lines just to get it to bite a little more but to answer your question typically smaller bore diameter’s means there’s less fluid for it to travel through and bigger bore diameter’s give you more fluid volume making the pedal softer and less responsive I hope that answers ur question thanks for watching I appreciate
I did this exact same thing to my 4x4 Tahoe and could not feel any difference. I don't see how people say huge difference. My brakes still feel as spongy as ever.
Then you did something wrong with the install or the bleeding
@@LowLifeYonkes That's the only I can think of also. Gonna redo it and hopefully it'll solve that.
Two days ago exited of the turnpike a little fast and I almost couldn't stop my Tahoe when reaching the red light. Freaked me out! Lol
@@MiamiWebDesign may sure u bleed the abs unit as well
Did u do that on the truck with the hood up if so what year model was it i have to do this on my 97 Silverado
Yea the hood was up kinda strange question but yea it’s a 98 c1500
@@LowLifeYonkes i figured it was that truck my guy wasn't trying to be on no weird shit thanks for the info
@@DeediLee ok glad I could help thanks for watching bro
If I get the brake bleeder tool I can bleed the brakes by myself ?
Yea u can bleed it urself if u buy the bleeder tool
I did it and it made it more harder to brake now it feels like if it did not have power brakes it feels like if u were steping on a rock ?
Probably bad brake booster
The Dorman M630031 I received looks like a piece of the bottom flange is broken off where it attaches to the booster, is that the design or a flaw? It arrived loose in the product box with no packageing and the box had a tear in it, so I want to know before I try installing it. Thanks!
No bro send that shit back it’s not supposed to be like that !!!
@@LowLifeYonkes Thanks-Subscribed!
What is the empty sensor plug for? Just did the swap to my 89. Thanks.
You can take it off it’s for the low brake fluid sensor
@@LowLifeYonkes thank you
Great video Thanks for the links!
Thank you for watching bro 👊🏼
@@LowLifeYonkes Earned a subscriber here!
Thank you I appreciate it !!!
Can I used that master cylinder on my 99 Cadillac escalade, 99 gmc Yukon ?
If it’s and OBS platform with no hydro boost yes you can use it
Just saw your Video, I was wondering could I do this on a 96 GMC Sierra Extended Cab? Everything Looks the same? Thanks!
Yes you can every thing is the same it works on 88-98 Chevy OBS
As luck would have it I just might sell one since my 89 just got wrecked last Saturday afternoon. Most likely a total loss.
Oh sorry to hear that .... shit happens sometimes it’s how u recover from it that matters bro .... thank you for watching!!!
Wondering if I should do this since mine all of a sudden goes to da ground n I changed break wheel cylinders in da rear where da leak was. You think it’ll fix it or do I have another issue?
Sound like u need to bleed all 4 corners and see where your at after that
@@LowLifeYonkes already bleed, changed wheel cylinders n bleed n pedal still goes to da floor
Sounds like the brake booster
Will this work with a master cylinder out of a 2004 Chevy 2500hd? I have one from that truck
No the fittings are different it won’t work I don’t think but you can try let me know how it goes …. Thanks for watching
Nice work! Subbed.
Thank you bro 👊🏼
It’s recommended to use a line wrench in order not to ruin the flats on the nuts
Yes I agree but I use what I have thanks for watching I appreciate it
Do i need to delete my ABS in order to install the NBS master brake cylinder? As i have 99 GMC suburban.
No you don’t need to delete it but it does work better if you do
Did you bleed the abs?
Yes bleed all line and the abs unit
What’s up man I just came across your channel and this upgrade it’s been about 8months that u did it how is it working ever since? Am about to do it
It’s the best upgrade I ever did it really works well it takes the spongy brake pedal away try it you won’t be disappointed thanks for watching
I’ve got to know I got the same but but when I turn it upside down and right side up it sounds like something is sliding or moving inside was your like that or no i’m trying to see if mines broken
Yes the new NBS master cylinder has a float inside when the brake fluid goes low it triggers a brake light inside on your dashboard. On OBS style trucks never had that that’s why you don’t plug in the sensor on the side of the new master
Did you keep the ABS if so, why? I hear a lot of people deleting this
Yea it’s still on there but yes I am deleting it as well I just about ready for the LS swap and I will also be doing some suspension work and deleting the abs
@@LowLifeYonkes If you could do a how to video on the ABS delete that would be great!
Good video. Sweet truck 👍 Is your truck stick shift, that's a bad little cruiser 👊
No it was a stick shift I got it on the cheap long ago the previous owner didn’t know what he was doing and swapped it he couldn’t finish it and I took over .... I’m guessing you saw the reservoir for the clutch I never took it out lol .... I want to put a stick back in it but we will see .... thank you for watching 👍🏼
Yes I seen the reservoir. I want to swap to manual, I have two transmissions with all that's needed from reservoir and lines with the clutch pedal and bracket. Just need the clutch kit and pressure plate. But really need down time since it's my current daily driver.
@@sereous67 I see u have 2 transmissions are they NV1500’s ??? And would you sell 1 of them ???
Hey guys, so I know there’s another video that says air gets trapped in the abs module and shows how to eliminate it. Is this necessary with the upgrade to the master cylinder? I was thinking I should do both. Mine is a 90 c1500 and the lines are different from the video I saw that was a 93. TIA
Ok let me see if I can help so 88-94 OBS trucks have a rear abs module only and a combination valve that the front and rear share so that being said there are 2 different procedures 1 for 88-94 and the other 95-98 both need to have a good bleed to get rid of any trapped air there are plenty of videos on both year of trucks but yes in either case bleed all the brakes and master cylinder and ABS model it makes a world of difference in ur braking power hope this helped thanks for watching
Nice video. That’s on my list as well.
Yea bro it’s a must do if you have one of these OBS trucks ! Thanks for watching
I’m still working on the inside and some light bulbs, speakers for the front door. Also the driver door key whole is hard to turn to unlock. All the power locks don’t go up and down. They click up and down but don’t lock/unlock. WD40 to the rescue
Hell yea bro get it done it will all be worth it in the end 👍🏼
It will be as it was my dads truck. I think we live near each other. I’m in Chino. Mine is a 1999 C3500 OBS crew cab 8ft bed

Good video I'm learning, it's good for a Chevy Silverado 1994 ,k1500?
Yes it works perfect 👌🏼 thanks for watching bro
Bro i just started having a problem with my obs when ever i step on the brake pedal it makes an air buzzing noise and its getting kinda hard to step on to im not sure if its the booster or the cylinder.
What year is it
94
Would this setup work on my 89 ovs k2500? It says it wouldn't fit but I just want to make sure before I buy it
Yea it should work they are all pretty much the same there is a few that are different but u should be fine thanks for watching
@@LowLifeYonkes no worries thank you boss, just didn't want to spend the money and not be able to use it

Will the SHORT Master Cylinder work in place of the OEM style 1991silverado ???
Yes it will
Does yours have a proportioning valve? Cus mine does. So idk if it would work with this mod.
No mine does not have one but my boy Chris has an 88 OBS and he does have a proportioning valve and it works on his as well
@@LowLifeYonkes ok cool thanks for the reply. I’m gonna have to try out this mod cus I’ve replaced almost everything and the brake is still spongy. Even sets off my brake light. Someone even told me that it could be the proportioning valve. Should I replace that as well? It got to the point where the brake sank almost to the floor 🙄
Try the master bro and if u have an abs module delete that shit bro it’s garbage 🗑
Buy it from Amazon free returns 😂
@@LowLifeYonkes im gonna try that and also delete the abs since you’re not the first to tell me to delete it. Thanks for the tips bro! #keepthemontheroad
Very clean presentation. Muchas!

Again, thanks.
Yes it will work as long as it’s not a hydro boost
Orale Hommie. Gracias for the tip. Gonna try this on my k20 burb.
Thank you for watching bro I appreciate it
Awesome video. 2 questions though. Did you have to bleed your brakes lines after at? Also does this fit the 94 model also?
Nope I didn’t bleed them after I’m a 1 man team most days and yea worked out well thank you for watching bro👊🏼
Yea it will fit
Did you do the abs delete?
No I haven’t done that yet
Did u have to bleed the brake lines .??
No I didn’t do it at first because I did it by myself but yes later I did bleed all the brake lines with some help from a friend
Will this work for a 1997 2500 with a hydraulic booster?
No it will not sorry
Did you have to bleed the ABS?
Nope just the master cylinder
Man I did this and I still have weird brakes idk what it is at this point nun of my breaks leak and I bleed them
Did you bleed your abs ?
Awesome presentation. How did you drain your master cylinder, use a bulb syringe?
Thanks bro …. I used an old plastic medicine kid syringe to drain it and the some old rags to get the rest …. Thanks for watching bro 👊🏼
No need to bench bleed the master?
You can but it was easier for me to do it on the truck when I mounted it
I'm gonna switch to the Long travel Master Cyl ...Large Resv. tank from Other videos to get POWER BRAKES Back.
Ok let me know how it goes 👍🏼
you ever wonder how much air is trapped in our abs modules?
After the swap was done I had a friend come over and did manual bleeding on all four wheels and the module not much of a charge for me but I did it anyway... thanks for watching
Well... did it work? Did it cure the feeling of stepping on a marshmallow? On mine I believe it is the ABS pump. I've seen a lot of videos where people go ham on masters, calipers, brakes, wheel cylinders all to still have the squishy feeling. The master doesn't drift or "vibrate" when depressing the brake, and the brakes engage and dont pull so its not like its a stuck caliper or wheel cylinder. The only thing left is the pump. At least I hope that is what it is because it cost 100 bucks. lol.
Yes it worked for me the brake pedal feels firm and grabs quicker than before no more squishy feeling .... after I was done with the install I had a friend come over and we manually bled the system and the abs unit as well it’s been working great ever since.... I’m actually getting ready to do agin to my other OBS 2 door Tahoe ... thanks for watching 👍🏼
@@LowLifeYonkes My next step will be abs delete using this setup. Thanks for the instruction. :)
Yes that’s my next move too lol I will post a video soon on how I do it
@@LowLifeYonkes Just wanted to come back to say with the new abs module and proper bleeding its a little better. At least I am not afraid to drive it now. But still not the greatest and I will be doing this upgrade. I am curious what these felt like when they were new. I used a power bleeder and like a gallon of fluid to be sure there was no air. lol. Have a good one.
