| Description of the problem | Complete brake failure occurred without warning except for a period of seconds during which "low brake fluid" warning light appeared. Vehicle was operating normally at all times prior to event. 38,111 miles on vehicle. Approx. 4 mile drive to highway, brakes working normally. While traveling 70mph (the legal limit there), warning light appeared. I immediately tapped brakes and found that pedal went all the way to floor. Managed to get to shoulder without accident. Drove gingerly to service station to examine. No leakage at calipers, on rotors or from any brake lines. Brake fluid reservoir empty. Had been full previously and vehicle well maintained. I filled reservoir with dot appropriate brake fluid, no change in braking ability. With pumping of pedal, no effect. With pedal all the way to floor, vehicle exhibited extremely attenuated braking (took well over 30 feet to slow from 10 mph to zero). Truck to ford service department/bay. They told me that "we see one of these about every week" which i found shocking. They rapidly diagnosed problem as master cylinder failure with bleed of fluid into booster system (which is why no pressure, but no leakage of fluid externally). They replaced the master cylinder and the booster. This is a very dangerous problem. Fortunately, i did not injure or kill anyone when brakes failed at highway speed. |
