I've bled the rear brake countless times, but the front two without any problem. Even after I bled the old brake fluid out, I've repeated the process as I added the new brake fluid 4 times making sure no air gets into the system and I'm seeing no air bubbles at this point. Fluid is going through and out, but I have very very little pressure a quarter way down, but if i press it pass that it gets softer then gets stuck, then I would have to lift it back up. Pump till I build up pressure, hold it down, open the bleeder valve, let it bleed, close the valve, then proceed to pump again. Right? I mean the front two were no problem at all. The rear disc is chewed up a little, but its not bad, and my pads are fairly new. I appreciate the help.
