Okay so my brake pedal in my 1995 mercury mystique GS had been a touch
soft and was getting softer, then jsut the other day i was driving
downhill and braking slightly when i heard a pop and the brake pedal
got softer, really soft. brought it back home parked it and
checked it out, there are no signs of leaks on the driveway, no loss of
fluid in the brake resevoir so i'm not sure it has anything to do with
breaking a brake line, but could it be the power booster being miss
tuned, or soemthing else?
