datzenmike Posted February 18, 2011 Report Share Posted February 18, 2011 Is one of them dragging? It would get really hot on the highway and maybe boil the brake fluid and the peddle will drop to the floor. Around town they would get hot but not hot enough. Take for a drive and feel the rim but watch out! They get HOT! Disc brakes seem to do this more than drum. Discs are on the front and the front does most of the stopping so any loss it really noticeable. Quote Link to comment
bonvo Posted February 18, 2011 Author Report Share Posted February 18, 2011 i dont think there dragging ill check though im thinking its somthing with the booster or i have some kind of blockage the whole system is gonna get flushed this weekend so im gonna go from there Quote Link to comment
benzo Posted February 18, 2011 Report Share Posted February 18, 2011 seems like you may also have a bad or failing master but check that booster also. also check for any leaking calipers and or leaking wheel cylinders. Quote Link to comment
datzenmike Posted February 18, 2011 Report Share Posted February 18, 2011 I've found that if the booster isn't working then the peddle becomes super hard to press down on. I had a spider nest over the winter in the open vac line on my truck. Took both feet on a rock hard peddle to stop in the driveway. It was the one way valve not letting vacuum into the booster.

bonvo Posted February 21, 2011 Author Report Share Posted February 21, 2011 i should update this i worked on it and found that the rear brakes were waaaaaaaaay out of adjustment and the pedal was also out of adustment im thinking that these 2 factors teamed with the fact that the brake booster makes the pedal drop a little at freeway speeds is what caused this issue im still going to test it but i beleve i have solved the issue Quote Link to comment
benzo Posted February 21, 2011 Report Share Posted February 21, 2011 yeah would like to hear the outcome. this is good info. rear brakes get looked over by many and lot of people don't know drum brakes can be adjusted or need servicing Quote Link to comment
