I have a 1990 Honda Accord LX sedan. My brake pedal was going pretty low to the floor, though not all the way. I was informed that my master cylinder may be failing. I bought a master cylinder from a used auto parts store, installed it, put new rotors on, new brake pads, new brake drums but the issue is worse. We didn't know to bleed the master cylinder when we first put it on, so we went back and did that, and bled the front brakes. Same issue, only now they are working intermittently. It seems my brakes work in the mornings, but by the end of the day, or as my car gets hotter, they go straight to the floor with minimal stopping power, somehow I manage. We just put on new wheel cylinder's on the back, re-bled the master cylinder, bled the brake lines, and my pedal is STILL going to the floor. The only thing we haven't replaced in the entire brake system is the brake booster. I have dished out $600 and gotten no where. Would a faulty brake booster be the problem, or could it be that the used master cylinder that I got, was also defective? If neither of these. What else could be the problem? I'm clueless at this point.
