You need to remove the caliper and suspend the caliper using a wire hanger. Remove the outboard shoe and lining, use a screwdriver to disengage the buttons on the pad from the holes in the caliper housing, and remove the inboard shoe and the lining, the bolt boots, the mounting bolt seals, and the bushings. Inspect the mounting bolts, the key, the spring, and the sleeves for any corrosion and replace any corroded parts. Then inspect the bolt boots for any nicks, cuts, or corrosion and replace any corroded parts.
