Pro tip: after bleeding the m/c, replace the cap on the reservoir. It will not leak while reattaching your brake lines.
I just did the upgrade today and the braking is so amazing. I realized that I need to adjust the drum brakes sometime soon and it will be A-1 braking. I did have a little leaking where the adapter screwed in but I tightened it down really good and it did stop leaking.❤😊 Definitely worth the swap for sure.
I’m glad it worked out for you thank you for sharing I appreciate it 💯
I had changed out my master cylinder 3 years back and then last year I had to replace it because the new one messed up and I thought about doing this conversion but at the time did not want to fool with it. This master cylinder after a year has already started messing up so I ordered the exact Dorman master cylinder same part number from Amazon and it was fairly cheap. I also bought that adapter from Advance Auto parts but it was $7.99 I believe before tax. It is well worth it. As a matter of fact as I'm typing this my master cylinder will or should be in Monday 4/22/24 and I already have the bleeder kit. I also use line wrenches or some people call them flare wrenches to prevent any rounding off of the nuts. I'm glad you showed me how to bend those lines because I have seen people take them off completely and reroute them all some kind of wonky way and it looks like crap but your lines still look really good and I never thought about putting my hand were the coiled part is and pushing down as I'm bending backwards on the lines to get them to line up. No pun intended. I'm glad you showed that and for anybody who is wanting to do this from what I heard it makes your brakes react so much quicker and you don't have so much pedal travel at all plus you don't have the spongy or squishy brakes that these '90s model OBS trucks came with literally from the factory. It's definitely worth it here where I live in Alabama because I live in an area that's considered the black belt which means these group of cities in a particular area in Alabama that is some of the best hunting so yes with that said there are a lot of deer that come out at night. I make about a 30 minute drive two and from work so an hour in total and just coming from work to home I could easily see 30 something deer if I count them so you have to be very careful and if you ever do have to hit the brakes having this upgraded mod will definitely make your brakes react a lot quicker so you can stop quicker to avoid an accident.
Thank you for sharing and yes this upgrade is a game changer like night and day difference for me and most people trying to upgrade there braking system thank you for sharing and watching my video I appreciate it
great idea while you're behind the master cylinder to give it a coat of paint 👍
It’s the small things right thanks for watching bro
I’m going to do this on at least 3 of my OBS GMs. Thanks for an informative video.
Thank you for watching I appreciate it 💯
I did this mod brakes did not feel good so I did a abs delete and put the nbs master cylinder brakes got better but did not have that brake power I wanted so I went back with the obs master cylinder and it feel great The best brakes I have every had
I like the obs master cylinder cause it has more travel more brake power
Interesting. Then you would think Chevy would have kept that style for the NBS models..but they didnt.
Awesome info, just did this update to my 94 extended cab. Love the channel!
Thank for the comment bro I appreciate it 💯
The one you purchased has an electrical plug on it?I just picked up a wearever brand master because they didn’t have doorman.it had a female electrical plug on it and of course my stock one doesn’t.
I appreciate the video and links! I'm gonna do my master cylinder on my obs Tahoe this weekend. This helped alot. Thanks!
Nice 👍🏼 thanks for watching bro I appreciate it
Another great video! Keep up the good work. Helping so many people out
Thank you for watching bro 👊🏼
Hey buddy.. I just wanted to say that you do great work and I appreciate what you're doing... thank you
Hey thank you for watching I appreciate it
So thus should fit on my 1998 chevy Silverado
Yea it will work
Awesome video
Thanks for watching Bro
What’s the difference between this master cylinder and the old one??? This is something I plan on doing
I have 2 videos on this upgraded master cylinder watch the first 1 but the main difference is the size the new one is much shorter making the distance shorter and making the brake pedal respond much faster thanks for watching if I have anymore quest just let me know
Great video bro! Keep up the good work. 👍👍👊👊🔥🔥
Thanks bro will do ! 👊🏼
@@LowLifeYonkes yessir! 👊
Great Job bro!
Appreciate it 💯
What’s better about this master cylinder than the original? Thanks for the video 👍
These trucks usually have spongy brake pedal that only stops when it’s far down so this master cylinder illuminates that spongy pedal and it’s a shorter firm feeling and of course the truck stops faster thanks for watching
Just finished the install works great but I will bleed each line individually anyway thanks.
Thank for watching glad it worked out
Do you have anything on passlock reset
98 chevy
@@calvinwade985 whats that ?
@@LowLifeYonkes where the security won't let the truck crank. The security light stays flashing
I need to do the same to my OBS.
This works amazing do it …. Thanks for watching bro 👊🏼
I have a C3500 will this fit for the replacement ?
As long it’s not hydro boost yes it will work
I have to research that. I have drums in the back and would like to upgrade the drums to disc brakes. Think I would do both at the same time.
Yea that would good to do them both at the same time
Is there a reason why you don't put a dab of white grease on the booster rod? Unnecessary? Also, do they make an adaptor that is made of steel rather than brass, or is that also unnecessary? Lastly, VERY nice job, taking that extra step to clean and paint the booster was awesome. I need to do this with my 1999 K1500 Suburban and it looks like I might be able to do it myself!
Ok the first question the new master cylinder has some grease where the push rod goes and as far as the adapter goes I haven’t found any other ones that work for this application and lastly thank you for watching I appreciate it
Will this work with rear drum brakes or will it make the rear brakes more grabby. Smooth video thanks.
This upgrade makes all the brake respond faster with less pedal effort stops at least 100% better
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
I replied to your first comment check it out thank you for watching
awesome video, will this nbs master cylinder work on a 98 C2500 pickup with 13" brakes?
It will work on anything that is not hydro boost and the brake size for 2500 and 1500 front rotors are the same size but the rear drum brakes are different
Did you notice a difference in your brakes after? Does the 88 year have abs if so how do you bleed the abs?
Yes big difference like night and day and yes the 88 does have rear abs only but it’s easy to bleed
Why is my brake pedal feel like it did not have power brakes like when its off it did not did that before ?
You probably have a different issue I have heard of this a few times in most cases it’s a bad brake booster
I was doing the swap on my 90 OBS but after i had the fitting in and the line in on the one furthest from the firewall it would not stop leaking. Is there a solution?
It’s the fitting look in the comments the answer is not all fittings are the same but they have the same part # the threads must go all the way to the bottom of the fitting otherwise it will never seal check ur fitting bro
Is this was cause obs to jerk back and fort when braking because of the old master cylinder ?
No I’ve never had an OBS jerk from the brakes usually the brakes are very hard and spongy when you press the brake pedal on an OBS this upgrade fixes that
Great video. Will that work on a 97 chevy silverado c1500??
Yes 👍🏼 it will work night and day difference
Where did you getting it again can you send me link please. Thanks a lot.
@@migo831 all links to parts used are in the description box
Short travel MC does NOT work in place of 7" travel MC. Will on longer have POWER Brakes!!!!!!
Bro your just having problems and looking to blame me because u can’t figure it out and it does work … time after time after time it works something else is not working in your truck and you need to fix it before you do this upgrade !!!!
@@LowLifeYonkes Not lookin for to blame anyonee!!! Lookin to Fix Probmem.
Did booster just die. How to test vaccume at booster!!!!
@@catdakman1273 you can put your foot on the break with out the moter running, with pressure on the pedal from your foot start the moter and if it goes down it's working, if not it's shot. That would tell you if the booster is working
What rear shocks do you use when lowered your truck?
Are you talking about my green OBS ???
I have tried this but the front line with the adapter leaked. The brake line moves/has play. Anyone else have this issue?
Yes the have it’s the adapter fitting u have to look inside the fitting and make sure the threads go all the way down otherwise it will leak manufacturer defect
@@LowLifeYonkes The AGS BLF adapter could have a defect with the threads going all the way down?
So I have a question I have 99 Tahoe with a spongy pedal will work on mine?
Yes it will it will give you that firm pedal feel
Is this with brake code jb3 for vacuum brake booster
I don’t know what jb3 is ?
@@LowLifeYonkes brake code in the glovebox
@@dallasstrickland5113 my glove box label is long gone I can’t see it any more
@@LowLifeYonkes ah that’s understandable. Thank you for responding anyway
Do you know how to bleed the abs system ? I have a 95 Yukon
Yea I do but I never made a video on it sorry
I have a 97 chevy 1500 4x4 does the Master Cilinder fits too. Or I have to get an Diferent time of MC
Yes this master will fit 👍🏼
@@LowLifeYonkes Thanks I been looking to do it
@@tonypadilla6404 thank you for watching
I know this is an old vid but i hope someone would be able to answer. I got a 97 k2500 and want to do this but i dont have a brake booster would you happen to know if it will still work ?
Is it hydro boost or just regular like the video?
@@LowLifeYonkes hydroboost
@@MrWilliewonka69 no it won’t work with hydro boost or at least no one has tried to install it that I know of sorry
What is the fluid you put in there? Just water?
Lol no bro brake fluid DOT3 …. Don’t use water it’s just clean brake fluid
By any chance Would this work on a 1987 Chevy c10
I’m not sure I know a few guys have asked this same question and I don’t know any one that has tried it sorry
Does the nbs master provide greater stopping power
Yes it does
Yes . I just did this swap based on this prior video . Definite big improvement even without bleeding the system . Be care when bleeding the brakes to not get air into the abs unit . A special diagnostic tool is needed . I did get air into the abs and it was 135.00 to bleed the abs at the mechanics
Right on I wonder if the obs reservoir would fit on the nbs master i like the separation between the front and back
@@daviddickerson3608 You can do it without the special tool. I did and mine work great, just crack the lines at the ABS unit. You might then need to test drive and engage ABS and then re-bleed but it was easy for me.
@@daviddickerson3608 did bleeding the ABS system make a difference in brake performance? I was told to bleed the ABS before doing the NBS swap.
The master cylinder you got had the electrical plug?
Yea it does it’s for the sensor but OBS don’t have 1 so I just left it there u can just unplug it from the master but I was lazy thanks for watching
@@LowLifeYonkes great content bro,very helpful.keep it up.
@@Cgarrison thank you for the support bro I appreciate it 💯
Quick question…. Is there a specific NBS year you look up to purchase? And is there a difference in 1/2 ton and 3/4 ton?
99-03 is what I look for and 1/2 ton
@@LowLifeYonkes estodo chingon! Thank you for the reply! You made an awesome video and I have a '99 K2500 Suburban I'm restoring and fixing up. I'll be looking at a lot of your videos
@@rickstir7144 thank you compa I appreciate the support 💯
@@rickstir7144 you'll need to get one for a say NBS new body style 2500
i believe 3/4 tons have a hydroboost vs 1/2 which is vacuum
is the nbs better than the stock obs one?
Yes it works 10x better than the original
Hey would this help with towing on my 92 k2500 with vacuum boost
You have hydro boost ? Or just regular booster?
@@LowLifeYonkes not hydro I believe it’s called vaccuum boost if I’m not mistaking?
@@justletmefish2323 does it look like the one in my video?
@@LowLifeYonkes sent you a message on Insta
What makes this an upgrade over stock M/C?
Watch the video and I explain everything u need to know
@@LowLifeYonkes why not replace leaking one with one of same type?
Just did this to my obs and the stoping power is horrible I have to pump my breaks to even get it to start stopping 🤦🏽♂️ any reasons why it would be doing that ?
Yea I would bleed the entire braking system including the abs module if that doesn’t work most likely you have a bad brake booster
@@LowLifeYonkesidk I put the obs master back in and breaks like it normally did lol I have bad luck when it comes to things like this lol gonna just end up returning the nbs cylinder was worth the shot your video did help alit bro 👌🏽
Does not work for 3500 1 tons just tried
I don’t know anyone that has tried it on a 3500 most of those I would assume are hydro boost
