I've been having problems with my wife's 97 pathfinder. The front brakes have been screeching for some time now and I have done everything I can to fix the problem. We took the car to PepBoys here in Puerto Rico, and they " change" the break pads, polish the brake discs, etc. We had to go three times because everytime we went as soon as we left the shop the breaks were screeching, and they said everything was in order. I decided to change the calipers because I noticed that pads were sticking to the brake disc, and the problem still persist.
