1999-2002 CHEVROLET SILVERADO 2000-2002 CHEVROLET TAHOE, SUBURBAN 2002 CHEVROLET AVALANCHE 1999-2002 GMC SIERRA 2000-2002 GMC YUKON, YUKON XL LOCATED IN THE SEVERE CORROSION AREAS LISTED BELOW Service Procedure The following procedure provides instructions for repairing a corrosion condition where the front wheel speed sensor mounts on the front wheel bearing assembly. 1. Raise the vehicle on a suitable hoist and support as necessary. 2. Remove both front tires and wheels. 3. Compress the front brake caliper pistons. 3.1. Install a large C-clamp over the top of the caliper housing and against the back of the outboard pad. 3.2. Slowly tighten the C-clamp until the pistons are pushed completely into the caliper bores. 3.3. Remove the C-clamp from the caliper. Important: It is not necessary to remove the front brake caliper from the bracket when removing the bracket in the next step. 4. Remove the two bolts that attach the front brake caliper mounting brackets to the knuckle. Notice: Support the brake caliper with heavy mechanic’s 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. 5. Remove the brake caliper and bracket as an assembly and support it with heavy mechanic’s wire or equivalent. DO NOT disconnect the hydraulic brake flexible hose from the caliper. 6. Mark the relationship of the rotor to the bearing hub. 7. If equipped, remove the rotor retaining push nuts from the wheel studs
