Thanks for the info, I talked to the dealer and they got my rear brakes fixed and i was able to talk to them a little more about the wheel cylinder. He said usually they would just be able to use one of those rebuild/repair kits but that in this case one of the wheel cylinders was actually so worn it had a hole through it which made it unrepairable at least to them. Im wondering if I might could have someone weld the hold in to make it at least useable. Anyone have thoughts on that or another solution? Thanks again for all the help!
