It has become hard to press the brake pedal down lately, and I am also having a hard time getting it to stop. I have listened to the master cylinder and can't here the seal leaking. I pulled the hose out of the power booster and it seemed to come out pretty easy. Does this need to be a snug fit? Any ideas to what the problem might be. My A/C won't blow very hard on high and the door on the passenger side under the dash is not opening. Do I need to change the vacuum dohicky behind the A/C controls to fix this. 1989 w/350, at.
