Sierra 3500 Denali 4WD V8-6.0L (2011)
Rear Disc Brake Pads Replacement (J90, J95, J96)
Removal Procedure
Warning: Refer to Brake Dust Warning (See: Service Precautions/Technician Safety Information/Brake Dust Warning).
1. Inspect the fluid level in the brake master cylinder reservoir.
2. If the brake fluid level is midway between the maximum-full point and the minimum allowable level, no brake fluid needs to be removed before
proceeding.
3. If the brake fluid level is higher than midway between the maximum-full point and the minimum allowable level, remove brake fluid to the
midway point before proceeding.
4. Raise and support the vehicle. Refer to Lifting and Jacking the Vehicle (See: Maintenance/Vehicle Lifting/Service and Repair).
5. Remove the tire and wheel assembly. Refer to Tire and Wheel Removal and Installation (See: Maintenance/Wheels and Tires/Service and Repair
).
6. Compress the brake caliper pistons into the caliper housing bore.
*
Install 2 large C-clamps over the top of the caliper housing and against the back of the outboard brake pad.
*
Slowly and evenly tighten the C-clamps until the caliper pistons are completely retracted into the brake caliper housing bores.
*
Remove the C-clamps.
Note: Do not remove the brake caliper guide pins unless replacement is required.
7. Remove the brake caliper bracket bolts (1).
Caution: Support the brake caliper with heavy mechanic wire, or equivalent, whenever it is separated from its mount and the hydraulic flexible
brake hose is still connected. Failure to support the caliper in this manner will cause the flexible brake hose to bear the weight of the caliper, which
may cause damage to the brake hose and in turn may cause a brake fluid leak.
8. Remove the brake caliper and bracket assembly and support with heavy mechanics wire or equivalent.
