My race truck is not holding on the brakes. It's a 94 with a hydroboost conversion, new napa power steering pump and I have swapped a known good booster in and still can't hold 25 psi well. When you pump up the brakes with the truck off it has great pedal. Start it and pedal doesn't kick back like it should. It also doesn't have nearly as strong of a pedal as I feel it should with the truck running. Kinda wanting to blame the 50 dollar napa pump. Anyone have any ideas?? I will say I havnt pulled the rear brakes apart yet to inspect but don't think that's the problem.
