Yeah, I think you guys are right. This sounds like what they were telling me yesterday. I was thinking of just leaving it as is but if there's a chance it could rust over I might actually do something about it. I think I remember them saying it may cause the pads to wear unevenly, something about the interior wearing before the exterior. That didn't really make sense to me, how could a rubber ring make a pad wear faster? The rust makes sense to me....rebuilding the caliper does sounds expensive though...ugh, stupid midas
