When inspecting my 02 MCS after I bought it from a private party, I noticed that the rear brake caliper piston seals are both torn. I'm worried about winter weather (salt and sand) getting into the area around the piston and figure that I need to replace them before they get too bad. Anyone know where to get new seals besides the dealer?

 

My early '02 rear caliper piston seals are torn too. Yes the winter will be rough on them. I plan on getting Wilwood's rear parking brake caliper, so new seals aren't too big a concern for me. That said, rumor mill has it a rebuild kit is not available for the rear calipers. Don't take my word for it though, call your dealer to make sure!

 

Ditto with Ryephile. I don't believe that you can get a rebuild kit for the rear brakes yet. You can get the boots from the dealer, but is it worth it? Buy the whole caliper, to insure no salt or debris has caused any damage already.
