Chevy NBS master cylinder on an OBS upgrade

[@107BATTLEBORN]

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!!😎

@@LowLifeYonkes You’re welcome. Question, bench bleeding, what exactly is that and what do you look for when doing the bench bleed? Thank you.

[@LowLifeYonkes]

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]

@@dusterdriven let me know if it does work

[@dusterdriven]

@@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 KZbinr recommending an alternative to our crapy obs/S10 master cylinder

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

I just completed this mod as well and I no longer have power brakes.

I did bypass the non functioning rear ABS so hoping that will help a little.

[@codyacklin1675]

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

[@LowLifeYonkes]

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

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!

[@LowLifeYonkes]

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

@@LowLifeYonkes just ordered it. Gonna install it mon

[@gregoenes1138]

I just got an 89 k2500, did you install this and if so, how easy was it and what are your thoughts on it?

[@noeltalamantes9701]

Did u have to bleed the brake lines .??

[@LowLifeYonkes]

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

[@israelgonzalez171]

No need to bench bleed the master?

[@LowLifeYonkes]

You can but it was easier for me to do it on the truck when I mounted it

[@kennethheadden2229]

Will it fit a 96 obs? It says on the Amazon link it won't fit

[@LowLifeYonkes]

Yea it will it’s a NBS master cylinder so it’s not made for the OBS but yes this is an upgrade huge difference in braking power

[@kennethheadden2229]

@@LowLifeYonkes mad respect for the reply. Love your obs sir! I've replaced my front right caliper on multiple occasions. It keeps failing and I replaced the hose too. Spongy pedal as well so I think I'm just going replace the master cylinder and bleed everything because it can't be the caliper every time.

[@LowLifeYonkes]

@@kennethheadden2229 yea this is definitely the way to go bro I have a few other OBS trucks this is the first thing I do every time

Great video, what yr of NBS works with 89 OBS?

@jkbrown72 yes

Right on!

[@sereous67]

As luck would have it I just might sell one since my 89 just got wrecked last Saturday afternoon. Most likely a total loss.

[@LowLifeYonkes]

Oh sorry to hear that .... shit happens sometimes it’s how u recover from it that matters bro .... thank you for watching!!!

[@TheObsBuild]

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

[@LowLifeYonkes]

Did you bleed your abs ?

[@jeyweb4236]

Same master cylinder can be used if you add rear discs.

[@LowLifeYonkes]

Yes sir same master can be used with rear disc !

[@LowLifeYonkes]

That year NBS came with both drum and disc brakes in the rear and it’s the same master cylinder !

[@americawhereareyou]

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.

[@LowLifeYonkes]

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 👍🏼

[@americawhereareyou]

@@LowLifeYonkes My next step will be abs delete using this setup. Thanks for the instruction. :)

[@LowLifeYonkes]

Yes that’s my next move too lol I will post a video soon on how I do it

[@americawhereareyou]

@@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.

[@xboxsk8]

you ever wonder how much air is trapped in our abs modules?

[@LowLifeYonkes]

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
