Brake pedal goes to the floor. I have a 1993 Ford F350. The brake pedal goes to the floor when the truck is running. The pedal is good when the engine is off. I have put a new booster on it, checked vacuum lines, bleed the brakes, measured the pads, rotors, drums, and shoes. All were good. Almost new in fact. I'm lost as what to check next. Any ideas?????? |
