Update to odi id number 10080842 - same owner; brake pedal master cylinder just started leaking again; has been replaced twice already; year 2000 vehicle has less than 42,000 miles on it; very costly repair to have to do every 2 years!.
Master cylinder on 2000 Ford Explorer has been replaced three times.
In early 2002 I noticed the brake pedal was feeling soft and practically went all the way to the floor with normal braking and the pedal made a hissing/vacuum noise at times. For hard braking it felt like the SUV wouldn't stop. I took the car for service on 6/8/02 at a Ford dealership which bled the brake system. This did not correct the problem. Took the SUV back on 11/9/02 and was told it was a vacuum leak from the power booster and the master cylinder was replaced. Pedal and braking was normal after this until recently, the brake pedal is failing again as before. I have not yet taken it to the dealer.
The consumer stated the brake pedal faded before the vehicle responded to the pedal. The dealer diagnosed master cylinder failure. When tested on gravel, only the back brakes worked which was only after the pedal was almost to the floor. Complete failure could have resulted.
