Rear
Removal and Installation1. Using a clear suction device remove brake fluid in the master cylinder reservoir until the reservoir is half full
2. 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.
3. CAUTION: Install new pads if worn to or past the specified thickness above the metal backing plate. Install new pads in complete axle sets.
Inspect the brake pads for wear or contamination Install new pads if worn to or past specification.
4. Remove the anchor housing spring.
^ Squeeze at the center of the spring until it unlatches from the brake caliper at both ends
^ Rotate the spring, then remove it from the caliper housing.
5. Remove the caps and brake caliper bolts
6. CAUTION: Do not allow the brake caliper to hang by the flexible brake hose.
NOTE: It is not necessary to remove the rear wheel brake hose when carrying out this procedure.
Remove the caliper and the brake pads
7. Using a suitable champ, press the piston into the caliper.
8. CAUTION: If machining is necessary, use a hub-mount brake lathe to machine the rear brake disc.
Inspect the brake disc. If it is scored it must be resurfaced.
9. NOTE: 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.
10. To install, reverse the removal procedure.
11. Install the anchor housing spring.
1 Insert the upper anchor housing spring end into the brake caliper cavity.
2 Rotate the anchor housing spring and position the lower arm onto the anchor plate.
12. Position the upper arm onto the anchor plate, then press down and inward until it is correctly seated and latched into the brake caliper cavities.
13. NOTE: The latch MUST be positioned as shown.
Verify that the anchor housing spring is correctly latched.
