Hi all, I was hoping for a little help here, as I am pretty dumbfounded by this. Let me start by saying that my brakes work flawlessly with no issues, other than the ABS light occasionally coming on. That being said, when I put my car in reverse and use my brakes there is a terrible grinding sound. It fells like something is trying to catch on the wheel or something, like the caliper is locking up. I just don't understand why it would only do it in reverse? Any help would be awesome. Car is 2000 Grand Prix, stock brakes.
