I recently installed the CSRP power brake kit and everything seemed fine except when I hit the brakes it goes down a couple inches and stops dead. The car stops but won't lock up. It just stops like the mc bottoms out, but when I unscrew a bleeder screw it goes all the way down. The vacuum line is hooked to the back of the carb and I'm running an Edelbrock RPM cam so not sure if that's hurting the booster performance. I have about 10 inches of vacuum at idle. Any ideas?
