| Brake Master Cylinder problems |
My brakes failed on two occasions. When the brake was pressed, the pedal sank all the way to the floor. This happened while the vehicle was in motion. Luckily, on both occasions, the car was moving at less than 25 mph. My ability to slow down was significantly reduced. Ultimately learned that the master cylinder was defective and had to be replaced.
