Is there a brake booster upgrade for 82-92 firebird i have a 1988 gta and im currently doing a LS1 brake upgrade im using a 1LE master from a 1989 if that matters i know there is a brake booster upgrade for 84-87 fiero when doing the grand am brake upgrade i know u use one from a s10/blazer like from a 1st gen blazer or s10 just wondering if the s10 one will work for our cars as well

Booster is never an issue here. So long as the master is matched for the brake setup.

Ah ok so i should be fine with the stock 88-92 master cylinder

I've long believed a 4.3L S-10 dual-diaphragm booster works better than most others, regardless of what it may be attached to.

Is there any benefit with the s10 booster when i had it on my fiero there was night and day difference in stopping and pedal travel

Wouldn't take much to grab one at the salvage yard and test it on your car. Not much risk, either.

Ok so year do i have to get one from is a 1993 or older best since those dont have abs
