• Q: How to Service and Repair a Rear Disc Brake Caliper on 2005 Jeep Liberty?

  A: Before servicing or fixing the rear disc brake caliper, set a prop rod on the pedal and then jack up and support the vehicle at its front. Disconnect the wheel and tire first and then loosen and remove the brake hose banjo bolt if you will replace the caliper. After that, remove the caliper slide pin bolts and take away the caliper from your car. When disassembling, first remove the brake shoes and then drain the caliper of brake fluid. Pour a layer of shop towels about one inch thick onto a piece of wood and fit the caliper piston into this cushion, then apply compressed air through the fluid inlet port to distribute low force on the piston until you can remove it. Don't keep blowing into the rifle to avoid breaking the piston and never attempt to catch the piston as it comes out of the bore. Lift out the dust boot around the caliper piston using a tool that won't scratch the bore and then carefully remove the piston seal with a wooden or plastic tool. Take out the bolts and bushings for the caliper mount that are protecting the boots. Don't use gasoline or similar solvents to clean the calipers; just use brake fluid or brake cleaners to preserve their condition. The piston should be free of cracks and smooth; replace it if scratched or with any dimpled surfaces and try not to fix a damaged piston. Beware: Mixing phenolic resin and steel pistons in the caliper will cause problems due to their incompatibility. Use a brake hone to fix little blemishes within the bore, but remove the caliper if the inside is too corroded or becomes too enlarged by your efforts. First, clean and dry where you will assemble, apply clean brake fluid to the caliper piston, new seal and piston, grease the interior of the bushing boots and caliper bushings with silicone grease, then assemble the caliper. Slip the bushings into the maincase, position the boots over them and once they are in the correct spot, push them down. The new seal for the mating surface goes into the groove first, then the new dust boot onto the piston, making sure everything fits in the right place. Turn down the caliper and use piston drop to lower it into the lower part of the bore. Apply Installer Tool C-4842 and the handle C-4171 to fit the dust boot into the caliper and then restore the caliper bleed screw if it was removed. Following removal of the brake pads, replace them, grease the disc brake's anti-rattle clips and pop the caliper using the caliper adapter. Place some silicone lubricant on the green mounting slide pin bolts, then bolt them up by hand and tighten them to 15 Nm. Mount the brake hose on the caliper with seal washers, avoid twisting it, tighten with the banjo bolt and torque release plate and tighten only to 31 Nm. Keep the wheel off the ground, unbolt the prop rod, bleed the base brakes and install both the wheel and tire once again before checking that the brake pedal feels solid.
