Break Specialist..I need help (Long)
About 6 mo. ago I had break failure, I mean no breaks what so ever. I dig into it and discover that what probably had happened is my front 2 rubber break lines were colapsing not allowing fluid to reach the calipers. (found this out after I had already replaced my Master Cylinder)
So, while I was in there, I decided to replace what I could afford. In addition to the MC that I replaced before I figured out it was my rubber lines, I also replaced Front Rotors, Front rubber lines, and front Calipers, all new, none remanufactured.
Everything was great up until about a month ago, and I developed a symptom that I also had before my breaks went out 6 mo. ago.
Whats happening is this.
Sometimes my break pedal is hard and all the way to the top, however with little effort of the foot, it stops the car with ease.
Other times it is what I would consider "normal", its not hard and is not all the way to the top and still stops the car with little effort of the foot.
With just that being said, it seems that it might be a Booster related issue, even though I have checked for vacuum leaks and found none, and there is no hissing sound coming from the booster under the dash.
When the pedal is hard, it appears the front driverside caliper is sticking. I say this for several reasons, one I noticed that when the pedal is hard and I come to a stop and let off the break the car stays stopped even while in gear (Auto trans). But when the pedal is "normal" the car will roll forward under the same situation.
Two, I noticed also when the pedal is hard, the front driverside wheel is about 10 to 20 deg hotter than the other 3 wheels, which leads me to beleive that the caliper is sticking, but will a sticking caliper, make the pedal feel hard and all the way to the top?
Sorry for the novel, Any help is appreciated.
