The car is a 1966 Mustang convertible, 289 2-bbI & C4 automatic. I installed the SSBC kit with front disk brakes, power booster and dual M/C in 2012. I'm on my third M/C (only one was actually defective) and all SSBC techs tell me is to keep bench bleeding. Done that many times, still no brakes. I can develop 1200 psi at the M/C port for the front disks, but not much braking effort when I stomp on the pedal hard. Just feels like the piston or the pedal is bottoming out with a hard, metallic feel. ?? Denney
