How to: NBS master cylinder swap for firm brake pedal

[Gzes]

Did mine just gotta bleed it. Only difference was i had to get another. I guess they swapped the fitting so i got one that was too small. Got another same size and it worked. Weird.. but yea i gotta wait to bleed it still stuffed and dont have the tools right now my dad does

Feels awsome. When i usedbto tow it felt kinda sketchy now with the mc its gonna be a brreze and can run heavier stopping from 30mph is about a 10ft difference for me justba guestamate but seriously a good cheap uograde. i paid $3 for adapter $0 for fluid cause i had new fluid and i bought the mc several months ago so very cheap n i am very happy

Quick input from my experience yesterday. Was haulin my 5th gen yesterday and had to brake from 75 to 0 in a couple hundred feet if that. We did it but barely. almost smacked into a semi and or taurus. If i woulda had the obs master cylinder we would have crashed.... Really recommend doing the nbs master cylinder upgrade

This should be stickied. Made my brakes so much better.

So I performed this mod on my dads 99 Tahoe and all went well. However I do have a question. The pedal is a bit spongy on top (did a quick bleed and going to the shop in a few days for a brake bleed) however it seems like it bottoms up half way thru and doesn't really go all the way to the floor like the obs master. Is this normal for the nbs master? Thoughts.

Yeah your pedal shouldn't go to the floor that's why this mod is available.
