I too have had a grinding noise while going in reverse down a driveway and I know for sure it's not scraping. Last night I got the grinding noise while slowly going backwards but I was in neutral this time which leads me to believe it really is the brakes and not the reverse gear/clutch! I also recently have been getting a high pitch squeeling while moving very slowly in reverse but not even touching the brakes. If I go different speeds in reverse the tone of the squeal changes but if I really speed up to 2-4 mph it stops. :(

edit: the grind noise sounds like an aluminum pan dragging under my car for 2 seconds, it's happened maybe every 3 days or so
