way to the floor, any ideas? It's a 1989 Chrysler Labaron 2 Door Coupe and just recently the brakes stopped working I heard a hiss like the car had air brakes and now the brake pedal sits on the floor pumping doesn't do anything , anybody have any ideas both taking the hissing into account and ingnoring it because I don't know for sure it was from the brakes and it wasn't me driving so I don't know.
