Removal & Installation
If the vehicle is equipped with air suspension, the electrical power to the air suspension system must be shut off prior to hoisting, jacking or towing an air suspension vehicle. This can be accomplished by turning off the air suspension switch located in the luggage compartment. Failure to do so can result in unexpected inflation or deflation of the air springs, which can result in shifting of the vehicle during these
operations. Failure to follow these instructions may result in personal injury.
Dust and dirt accumulating on brake parts during normal use may contain asbestos fibers from production or aftermarket brake linings. Breathing excessive concentrations of asbestos fibers can cause serious bodily harm. Exercise care when servicing brake parts. Do not sand or grind brake lining unless equipment used is designed to contain the dust residue. Do not clean brake parts with compressed air or by dry brushing. Cleaning should be done by dampening the brake components with a fine mist of water, then wiping the brake components clean with a dampened cloth. Dispose of cloth and all residue containing asbestos fibers in an impermeable container with the appropriate label. Follow practices prescribed by the Occupational Safety and Health Administration (OSHA) and the Environmental Protection Agency (EPA) for the handling, processing, and disposing of dust or debris that may contain asbestos fibers.
Before continuing with this procedure, make sure to have available, 2 banjo bolt sealing washers, per caliper. Once removed, these parts loose their torque holding ability or retention capability and must not be reused.
If equipped with air suspension, the air suspension switch, located on the right-hand side of the luggage compartment, must be turned to the
position before raising the vehicle. If equipped with a fire suppression system, depower the system.
Remove or disconnect the following:
Rear wheel and tire assembly
Banjo bolt securing the brake hose to the disc brake caliper. Plug the brake hose and discard both sealing washers.
2 disc brake caliper locating bolts. Lift the disc brake caliper off the rotor and anchor plate using a rotating motion.
Retract the disc brake caliper piston fully in the piston bore, using an old brake pad or block of wood and a C-clamp.
Install or connect the following:
Disc brake pads on the caliper. Make sure that the pads are on the correct side.
Caliper assembly above the rotor with the anti-rattle spring located on the lower adapter support arm. Install the caliper over the rotor with a rotating motion.
Clean the inner surface of the caliper bushings and locating bolts. Lubricate the caliper locating bolts with a suitable silicone dielectric compound. Install and start the locating bolts by hand only. Torque both bolts to 27 ft. lbs. (36 Nm).
Brake hose, after unplugging it, to the disc brake caliper using 2 new copper sealing washers on the banjo bolt. Torque the bolt to 35 ft. lbs. (48 Nm).
Bleed the brake system, filling the master cylinder as required. Only use clean DOT 3 brake fluid from a sealed container.
Replace the rubber rear disc brake bleeder screw cap.
Install the wheel and tire assembly. Torque the lug nuts in a star pattern to 100 ft. lbs. (136 Nm).
If equipped with air suspension, turn the air suspension switch to the
position. If equipped with a fire suppression system, repower the system.
Pump the brake pedal several times to position the brake pads prior to moving the vehicle.
Road test the vehicle and check for proper brake system operation.
