I have a 1998 chevy k1500 4wd, front brakes wer bad and I had to replace the front pads and calipers. Now the pedal while vehicle is running is soft, when I first hit the peddle, I can pump it and and its a little harder. Vehicle always stops. When vehicle is off pedal is hard and holds pressure. When running pedal goes soft. I un hook vacum line to booster and the pedal is hard, hook vacum line back up peddle is soft. Does this mean the booster is bad? Can I drive with the vacum line pluged till I replace the booster if it is bad?
