Ok, working on the brake system, 4 way disk brakes, right stuff proportional valve, Cardone master cylinder and power booster.Made my own lines leaked all over, took lines off and had a shop do all the flaring- no more leaks. Bench bled the master cylinder, hooked lines up, pump the pedal and have fluid at all the bleeder valves. I open the valves and some air came out, (not as much as i thought for a dry system) and then only get fluid. I started at the rear passenger side, rear drivers side, front passenger side and then the front drivers side. I get NO pressure build up. I made the brake pedal for this car - the rod to the master cylinder moves about 3/4". Is this enough, redo pedal get more stroke, is my proportional valve bad, master cylinder bad, don't know really what to tackle next. Thanks for help.
