Hey everyone I have a 95 Gsr. When I first got the car the front shook when I pressed the brake so o replaced the rotors and the pads fixed that but since I've had the car 3/4 the time the brakes fall the the floor when im stopping. I've bled all four calipers but they still fall the the floor like when im slowing down or stopped. A few times when stopping they go all the way and only one caliper works and it pulls so hard to that side. I figure Ts the master cylinder and just wanna make sure before I put this b20 in the so I can go ahead and swap them. Let me know your opinions thanks.

b20 again?! lol. i would say it was the master cylinder as well. make sure none of your calipers are leaking either.

No if it were the brake booster failing, the pedal would be hard to push, but wouldn't fall to the floor. Are you using the proper brake bleeding sequence? Its Right Rear, then Left front, then left rear, then right front.
If the MC is bad, check the hose from the brake booster to the intake manifold and smell for brake fluid. Thats one clue. Also Push the pedal a couple times quickly in a row, this can build pressure. If it does, it could also mean the MC is dying.

incorrect. if the booster failed internally allowing vacuum at all times into the diaphragm, it would pull all the way to the floor. the check valve inside the booster fails and causes this. time for a new booster if this is the case.
