Brakes are fine unless you REALLY-MUST-STOP- NOW.

Hi All,

New to this excellent forum and have a brake question. I have a 1969 Camaro RS with 350 and a 4 speed. I just finished installing DSE rear 3" lowering springs with Delrin bushing/shackle kit, Viking double adjustable rear shocks, SpeedTech tubular upper/lower control arms, Viking double adjustable front coilovers, Unisteer rack and pinion, rebuilt tilt steering column, The Right Stuff 8" dual diaphragm vacuum assist with 1 1/8" master cylinder, Baer SS4 front 11" disc brake kit, Baer Iron-Sport 11.6" rear disc brake kit, 18x9.5 Vintage Wheel Works 2 piece type V40 rear wheels w/ 275/40-18 Hankook V12 tires, 18x8 VWW V40 front wheels w/ 245/40-18 Hankook V12 tires.

The original plan was to retain the 15" rallye wheels which is why I went with the smaller brakes, but I ended up buying 18's anyway. I find the car stops infinitely better than the original 4 wheel manual drum brake setup. HOWEVER, the car won't lock 'em up in a panic stop situation. Will a smaller diameter master help this issue, or did I simply make a mistake going with a 8" dual diaphragm booster? I'm not sure what cam is in the engine, so not sure if it just low vacuum, but even after driving and letting off the gas while in gear, shouldn't it make enough vacuum to function properly? Any ideas would be awesome. Thanks.
