I haven't had any luck finding out if this is a common problem, so i will post it here with the hope that someone had the same problem. Basically, my rear brakes are rusting pretty heavily compared to the front (I only have 31000 miles) and was told when i did one of those quick lane inspections back in july that I would need new ones in december. When I questioned the service guy about it he really didnt know why, but did make sure to tell me they could do it for $2000 dollars. Im just wondering if there is a fix to this problem or should i just get new brakes, as my front discs do not have the same problem. It is an automatic, but i do use my parking brake every time i park, i don't know if that makes a difference.
