I got gsr brakes for all four, trailer arm and all......I installed it and everything works, just that my brake pedal is soft(I have to step on it all most all the way for it to catch) even after bleeding it. I did some research and I thought I needed a master brake cylinder and brake booster...so I got 1 from a 95 integra from the junk yard and when I installed it, one of the holes in the master cylinder for my stock brake lines to connect to is bigger? There are 2 threaded holes on the master cylinder for my brake lines..... 1 fit perfect the other don't....help a tuner
