2000 GMC Jimmy 6 cyl Four Wheel Drive Manual 108000 miles
Brake problem: Soft pedal that will travel to the floor when engine is on. I have bled the system, and changed the master cyl. The pedal feels great when the truck is off. ABS and Parking Brake lights come on after a few minutes of driving. Proportioning valve? The vacuum check valve seems ok on the booster. The vac line seems fine too. What do I need to do? Thanks a ton.
