My brakes don't seem to be what I was expecting for 4 corner discs,it does stop but not spectacular.Parts are:CPP rears,SSBC 43mm 2 piston frts,11" booster.Will these work together or are they fighting ?:confused:

What was the original setup?

How much vacuum are you pulling at idle? Looking at the engine stats in your signature that could be part of the problem. I was told when I bought mine that at least 16" was needed on the 11" booster for good performance and the more the better with four wheel discs.

What car?

orig.was all drums,need to get vac.guage and check it out !
