I've been trying to find a caliper rebuild kit for my 2004 front brake's. My local automotive stores don't have the kit. Where can I find please? Thanks

I think what you are looking fore is the GM kit: #12530686 - Front caliper kit, #12530687 - Rear caliper kit. This rebuilds (calipers, the piston seals, guide pin boots, and so forth).

Then kit up your local dealer with those part numbers and you should be good. :cheers:
