Process of elmination right?
I had the problem awhile ago with my brakes being soft after I replaced the front pads and put on a new master cylinder.
Well it never really got completely fixed and while I could still stop safely it just didn't feel like it should. I've bled the thing a ridiculous amount of times and every time it will be ok for about 5 minutes then it goes back to how it was.
I've been doing some research and a sinking pedal is a symptom of a bad proportioning valve. Quite frankly it's the only thing I haven't replaced. Any opinions or ideas?
FYI: No fluid loss, new brake lines, new master cylinder, Vacuum booster is good, drum brakes are good. Pedal has little to no feed back until closer to the floor.
