This is my first post. I'm hoping someone can help me. My 2002 dodge grand caravan has squeaky rear brakes when going slow backward or forward even without pressing brake pedal. The van has been sitting in the garage for 3 weeks while I have been doing body work on it and when I first started it up it didn't even want to move in reverse or drive. I thought it might be because I had removed the automatic sliding door to paint it. It finally moved but now the rear brakes squeak terribly. Any ideas?
