ok i'm getting an 86 gt-s back on the road. It had fueal delivery problems. which turned out to be a bad pump and a clogged return line. that issue is solved. next up is the brakes. when i started the last owner had put a new master cylinder on but had gone no further. i bled the MC out and proceeded to bleed the entire system. the problem is after i was done was that the pedal went only about halfway down and felt like it was hitting something and stopping. while test driving i pressed the pedal and it popped and sunk almost to the floor. now it is catching near the bottom and seems to be catching more back brakes than front. I was wondering if anyone has had that happen or just knows what is causing it.
