My Right front wheel drags when i back up in my Pontiac. Im not sure if my transmission had something to do with it, because when i sprin my wheel (so the tire goes backwards) the tranny wines. But it feels like brakes are sticking only when backing up. I didnt have enough time to take the wheel off because i was working on my exauhst and had to get to my next class. So could my brake lock up like that going backwards and not forwards?
