    Somewhat common of an issue in the salt belt areas.

    Aluminum caliper + steel piston + steel slide pins = corrosion. Be sure to remove the pads as well as the pad slider clips (stainless steel plates on each side of the pads) and clean the grooves out in the caliper bracket. They're famous for getting corrosion buildup behind the slider plates..which then wont allow everything to float freely, causing drag on the pads. Usually need a chipping hammer and a coarse file at pad replacement time in order to clean the pad grooves out on most any brand of truck with rear disc's in the salt belt. Use plenty of silicone brake grease at reassembly as well. Often overlooked detail at many repair shops.

    No not saying that as it still may need the caliper changed due to piston to caliper body corrosion.

    Just be sure to clean everything else of rust/corrosion while you have it off or you'll be in there again for similar symptoms again.

    if your piston is seized up then you need to replace caliper and I have had better luck with Napa IMO they sell you the whole thing frame and all not just piston like advance auto for ussually 20.00 more not worth all the trouble if you ask me but I just got done putting brakes on my grocery getter 04 impalla calipers and everything brake hoses..I used to have a gmc and at 30000 miles had caliper go bad but was covered under waranty disc on the back = trouble alot of the times drums are alot less hassle..
