Ok, I need some help. 75 dart front disc, rear drum, new brake lines, hoses wheel cyls. and Master cyl. The brake pedal will not return to the full rest position after applying brakes. I have to pull the pedal up with my left foot. I checked the booster for any vacuum leaks, none. When I remove the vac. hose from the booster and plug it off at the manifold the pedal returns normaly, and of course the pedal fells soft. I've bled the system several times, both pressure and gravity, no air in the system, so I guess my question is with the booster not having any leaks could it still be bad? The brakes worked fine before the resto, but now I can't seem to make any progress on this issue, any help or idea's would be great. I did notice last weekend I took it on a little road test and the pedal will go in so far and then make a fast movement downward and really applys the brakes, then you have to pull the pedal up by hand or with you foot. About ready to give this car stuff up and find something less costly and hassle to spend my money on, tired of this money pit.I work on it more than enjoy it.

Yes I've had parts go bad from sitting esp several ign boxes that worked fine when parted and were not jostled in storage but for sure went bad in a certain length of time (maybe a year). When I get to feeling rabid I have to step away for an hour or a day & get calmed down. I'm not a PB guru but might check the pushrod clearance to the bottom of the piston recess (~1/8") though it sure sounds like a classic booster prob

Back when I restored my Challenger I had been driving it for about a month when the booster failed... It had been fine then one day backing it out of the driveway the pedal pulled hard down to the floor & the car wouldn't move at all... Thank god it didn't happen while I was driving at 70+ MPH on a curvy mountain road... The booster had been rebuilt but apparently an Oring got pinched or something... Anyway like Robert said, change out the booster.. Hopefully the car will hit the point where it settles into being a fun reliable driver...
