Everything has been installed. I already bled my brake system but the pedal is dropping down to the floor board. The brakes are grabbing. I think I have a problem with the booster. There was a hissing sound coming from the booster while the engine was idling and even after I turned off the motor you could still here the sound. Vacuum leak? Bad Booster? Took it for a test drive and the motor stalled and would not fire up again. I have spark and fuel. Could this all be caused by a vacuum leak from the booster?
