My powermaster motor is not kicking on when I turn the key on like it used to. The brake light in the dash is staying on and I have no power brakes (pedal is extremely hard). Does this mean the whole unit is shot? I have a remanufactured unit on there right now from 2001. It has a lifetime warranty and thank goodness I have the original receipt. I called the local parts store and they will have the new one in tomorrow. I paid $260 back in 2001 and now they are about $500
