whats wrong with my brakes?

[Musclerodz]

With that booster and those brakes, you need 1 1/8 master. Install a set of reduced angle booster brakes and redrill the brake pedal just under the manual hole on the pedal. Another thing is you need to bed the pads. They are probably glazed at this point making the feel worse. Its not ideal vacuum, but the dual diaphragm booster should be able to keep up. If not you could be real slick and use a RS vac cannister as a reservoir.
