I have had a spongy brake pedal for the last 5 years and its starting to annoy me that the brakes barely work on my car. A few years ago I switched out the master cylinder because it was leaking out of the cap and out the back, but once I installed the new one it did the exact same thing. Just yesterday I pulled the master cylinder and bench bled it to make sure it was done properly, and then I bled each wheel. None of the wheels seemed to have any air in the lines. I cannot find any leaks anywhere in the lines, the only thing that leaks is that master cylinder out of the cap and from the back where it bolts to the booster. I just don't understand whats going on. I'm thinking maybe something is wrong with the proportioning valve or the booster? Is the master cylinder bad?
The back brakes seem to be OK, and doing there job, but the front brakes barely do anything unless I push the spongey pedal all the way to the floor. I am on the verge of buying an entirely new system, lines, mc, everything.
