Brake Booster??
Hey eveyone I picked up a project car to work on about 2 months ago and I have a brake question for you!!
CAR: 90 80Q (NON-ABS)
The brakes work fine while driving but upon pulling upto a stoplight and sitting for about a minute (takes less time the hotter it is) my brake pedal will slowly start to drop to the floor. The brakes never let go, it's just a little nerve racking!! It only tends to happen when it's 80+ degs out. When it's cooler out I have absolutely no problem with the brakes and as I said they work perfect stopping...the problem only comes when brake is depressed for an extended peroid!!
Since it's related to heat(and therfore humidity), it makes me think that I must have a bad seal, but on which part? Is that a sign of a bad brake booster or master cylinder? Or can just a little air in the lines give those symptoms??
Any Advice Appreciated(AAA)!!!
