gm part number 5466562 --this should be the piston seal and the square profile O ring that fits into the bore of the caliper.
Actualy No My local parts stores don't even carry rebuilt or loaded calipers Thats why i would rebuild mine Like we use to in the old days, pglade thanks for the # Dave
www.gmpartsdirect.com--$8.69 per wheel. However, I think it is more cost effective to just buy rebuilt calipers from NAPA.
if you are cleaning up your calipers and painting them then take note---do not paint the small circular area where the crush washer (for the brake line) meets the body of the caliper---this needs to be clean bare steel for a good seal on the crush washer. Patton
I got a pair of seal kits from Advance Auto Parts. Believe it or not, they have a lot of parts for our cars. I got a reman master cyl and booster for just under $100. The brand name was Cardone which is what Napa sells for $130. They also had Cardone reman loaded calipers for around $50 ea. I got all my brake lines there too.
I found my kits in my toolbox. They're made in USA by Allparts Co.(Tru Torque) in Louisiana, Missouri. The part # is D35494. There is four other cross reference #'s from other companies as well.
