REMOVAL & INSTALLATION
- Raise and support the vehicle safely.
- Remove the rear wheels.
- Disconnect the brake hose from the caliper. Plug the end of the hose to prevent loss of fluid. Discard the union bolt gaskets and replace with new ones.
- Remove the bolts that attach the caliper to the torque plate.
- Lift up and remove the caliper assembly.
- Installation is the reverse of the removal procedure. Grease the caliper slides and bolts with Lithium grease or equivalent. Torque the caliper bolts to 14 ft. lbs. (20 Nm) for rear disc brakes. Fill and bleed the system.
- Remove the caliper from the vehicle.
- Withdraw the two slide bushings and dust boots from their respective slide bores.
- Remove the dust boots and sliding pins from the torque plate.
- Gently pry the cylinder boot set ring from the boot and remove the boot.
- Place a folded towel or piece of wood between the piston and housing. Apply low-pressure compressed air to the brake line union fitting to force the piston out of its bore.
Be careful, the piston will come out forcefully. Do not attempt to catch the piston with your fingers, since injury will result. Wear eye protection.
- Pry the piston seal from the bore.
- Check the piston and cylinder bore for wear and/or corrosion. Replace components if excess wear or corrosion is present.
- To assemble, coat all the bore, dust boot, collar, slide bushing, piston and piston seal surfaces with lithium soap base glycol grease.
- Install the piston seal into the bore and install the piston using a hammer handle or equivalent.
- Install the boot and set ring.
- Install the collar, dust boots and boot bushings in the torque plate. Make sure that the boots are secured firmly to each brake cylinder and bushing groove.
- Install the brake pads into the cylinder and install the cylinder onto the torque plate. Torque the caliper bolt(s) to 14 ft. lbs. (20 Nm).
- Fill the master cylinder reservoir with fresh fluid and bleed the brake system.
- Pump the brake pedal and check the brake system for leaks.
Make sure to pump the brake pedal before moving the vehicle. This will seat the brake pads against the rotors, otherwise the vehicle may have no braking.
