This is in my 90 Dodge Ram not the A-body but brakes are brakes so was hoping someone would have some ideas. I lost my brake pedal pressure the other day out of the blue, pedal went to the floor but with a few pumps it comes back up. You have to do that each time. Had a look, the brake shoes were toast, replaced those, one side of the e-brake was seized, replaced it, bled everything, no difference, oh, wheel cylinders are fine and no line leaks. Put in a new master, bench bled it and all, it's even worse now, no pedal and it only comes back a bit. Any ideas??
