I have a 2003 Ford Escape 3.0l V-6. In June while driving to a job interview, my brakes unexpectedly failed. With absolutely no warning, the pedal went straight to the floor. I replaced the master cylinder…problem solved. 5 months later, driving to the gym, after stopping successfully several times with no mushiness in the pedal, at an intersection, the pedal goes straight to the floor…no stopping power.
I can’t remember if the brake light came on last time. This time it did. Both times the fluid in the reservoir was full and looked to be relatively clean. Both times there were no apparent leaks in any of the fuel lines, abs module, at the cylinder, etc. I’m no slouch when it comes to car repair. The master cylinder replacement was done correctly, the lines were bled properly.
I have my own theories but I don’t like any of them as my car rolls properly at idle, my brakes have not, nor do they currently make any noise or grinding sounds, and the pedal goes all the way to the floor. Your thoughts?
