Brake pedal pressure disc conversion
I completed a manual to power and drum to disc brake conversion on my 66. I used spindles, rotors and calipers from a 71 mustang along with the 71 proportioning valve . I bought the SSBC booster kit with master cylinder. I've bench bled the master cylinder twice. Bled all the lines several times and am not getting any air. My problem is brake pedal pressure. It's weak. The pedal also travels about 1/3 before the brakes start to grab. And when it does as I said the pedal pressure is weak. I've adjusted the adjustable brake pedal rod and it doesn't help. Calipers, pads, lines, rotors, master cylinder and booster are all new parts. Do I have a bad master cylinder? Anyone have any thoughts or suggestions?
