new pads, new master cyl, new caliper no brakes
1999 mustang 3.8 manual no abs no tc.
so a couple weeks ago I was driving and heard a pop/clang noise lost brakes and then the left rear tire locked up. took it apart and the caliper seized up all the way open. so I put a new caliper on all new pads bled the system got all the air out. but still no brakes pedal just hits the floor no pressure at all. so I went and go a master cylinder. bench bled it till there were no air bubbles in it installed it bled the whole system again TWICE and still no brakes. when the engine is off the pedal is stiff as a rock but very slowly goes down. engine on it just hits the floor. no hissing sound from booster but I did take the vacuum line off of it and turned car on and pedal only goes down halfway semi stiff. I read as many threads as I could find but I'm still stumped. ive heard check valve or maybe diaghram in booster is bad?
