Rear

Brake Disc

Removal and Installation

1. WARNING: 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 RH kick panel area. 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.

Remove the wheel and tire assembly.





2. NOTE: When removing the rear disc brake caliper in this procedure, it is not necessary to disconnect the rear wheel brake hose.

Remove the brake caliper anchor plate bolts.





3. CAUTION: Do not allow the brake caliper to hang by the flexible brake hose.

Remove the anchor plate and caliper as an assembly.

4. NOTE: If the brake disc binds on the parking brake shoe, remove the adjustment hole access plug and contract the parking brake shoe.

Remove the brake disc.





5. CAUTION: If machining is necessary use a hub-mount brake lathe to machine the rear brake disc.

NOTE: Inspect the brake disc. If it is scored, it must be resurfaced. Also, resurface the rear brake disc if a test drive has identified vibration transmitted through the steering wheel, seat or brake pedal while braking.

Measure the rear brake disc, and resurface as necessary. Install a new rear brake disc if beyond specification.
6. To install, reverse the removal procedure.
