Thread: '57 Brakes

Tweet

I have a 57 Chevy Belair and have installed 70s Chevelle power disc on the front and matching master cylinder for front disc/rear drum brakes. I want to put a 1980 Pontiac Firebird 10-bolt posi, disc brake rear end on, and was wondering whether to go with a 4whl disc Firebird master cylinder and proportioning valve or should I use an adjustable proportioning valve instead? I already have a power booster unit from an 80s Citation. I'd appriciate any input. Thanks.

If it were me I'd try the firebird stuff first.

use a wilwood adjustable valve , you can fine tune it better . i have a 57 sedan with 4 wheel disc and no porp.valve and it has great brakes also .

Thanks for the help guys. I think I'll try the Firebird master cylinder and an adjustable proportioing valve.
