This rear caliper rebuild should cost around $25 and take about 45 minutes to complete.
Brake fluid will damage almost everything it touches, so make sure you have your shop towels ready!
Check the caliper components for any visible damage. This piston has a few rough spots so I will need to sand them down. Check the slide pins for any rough areas that could bind. If you feel anything, gently sand it with fine grit emery paper until smooth.
Measure the inside diameter of the piston bore and the outside diameter of the piston.
The piston bore should be no Greater than 22.712mm, and the piston should be no LESS than 22.573mm.
Before caliper assembly, take a look at your new parts.
I am installing an All Balls Rear Caliper Rebuild Kit that includes a new set of slide pin boots, pad pin o-ring, bleeder valve cap, piston seals, pad pin, and banjo bolt seal washers.
Make sure to match the old parts with the new ones, so you don’t accidentally discard something you need.
