Im having a problem with my brake pedal. When i press on the brake pedal, the pedal wont release back, and the brakes stay on. I have a vacuum brake conversion, and have replaced the brake booster twice, replaced 2 master cylinders. I have also bled the brakes. My setup is billet alluminum vacuum block, 87 monte carlo dual diaphragm/master cylinder/brake pedal. I noticed with the new boosters that the pedal is not as far forward as it could be. I have lots of vacuum. For pedal feel, it starts off extremely firm then goes soft and then doesnt release back or takes a while to return. The brakes are dragging until the pedal returns. I am at a standstill since i cant even drive the car! I need help please!

Loosen the M/C, slip a THIN ft end shim over each stud, tighten up. Try it again. If the booster ft pin is out of adj, it may be causing the M/C to fail to return, trapping fluid.
The M/C has the correct p rod cup in it, correct? Some cups are deeper/shallower than others.
