My GF's 92 ford explorer had horrid brakes (there was a metal ring that was the outside of the rotor that fell off when I checked the brakes... scary!), so I replaced all 4 wheel's brakes. Calipers, wheel cylinders, rotors, pads, shoes, and wheel bearings. The front lines looked old but not terrible. I bled the system fully twice.
I took it around the block after doing this and adjusted the rear brakes until I felt like the pedal was about right. I also checked each brake for heat to make sure they were all engaging.
The car seemed great after this- brakes worked well, no problems. But now twice the pedal has just gone to the floor on her without the brakes engaging at all- no resistance, no stopping. She pumped them the first time and the brakes came back. The second time she pumped and pumped with no success, so she had to use the e-brake to stop and park the thing.
I had her check for leaks 45 minutes after this second time and there were none, but the brakes had magically returned to fully functioning .
I'm thinking its got to be the master cylinder, but I've never seen one fail personally so I don't know the symptoms. Am I right or is some ABS nonsense responsible?
thanks a bunch in advance!!
