2003 Ford Taurus 6 cyl Front Wheel Drive Automatic 90000 miles
The brake pedal started going to the floor( evidence of leakage from rear of master cylinder also), so I replaced the master cylinder( I bench bled it) The problem continued so I replaced it one more time. Same thing. When the engine is off I can pump the brakes up to a good height and pressure. As soon as the engine is stared the pedal falls to the floor. No leaks were detected around the wheels.
