• Q: How to Effectively Service and Repair a Brake Caliper on 2001 Jeep Wrangler?

  A: Take out the brake shoes and drain the brake fluid from the caliper as the first step for servicing and repairing a brake caliper. Lay a pad of one-inch thick shop towels on a piece of wood and attach it to the caliper, facing the outboard shoe and in front of the piston to make sure it doesn't touch anything during removal. Give a quick blast of low-pressure compressed air through the fluid inlet port to get the piston out, making sure the stream isn't too strong to avoid damaging the part and never put your hand where the piston could hit it. Take out the dust boot from the caliper piston with suitable pry and then get rid of the caliper piston seal using a wood or plastic object to protect the piston bore from scratches. After that, take out the caliper mounting bolt bushings and boots. Right before assembly, clean and dry the area so that caliper seals are not damaged. Spray clean brake fluid onto the caliper piston bore and the new piston seal, then the new piston with brake fluid and coat each caliper bush and interior boot with silicone grease. Fit the bushing boots into the caliper, get the bushings into the boots and smoothly insert the entire assemblies. Put the new piston seal into place with your finger, followed by inserting the new dust boot on the piston and settling it into the piston groove. Press the piston into the caliper bore, turning it as you push, to secure it carefully in the groove and then bring the piston all the way down. Once done, fit the dust boot in the caliper with Installer Tool C-4842 and Tool Handle C-4171 and if you took out the bleed screw, put that back in place as well.
