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.
