INSTALLATION PROCEDURE

NOTICE: Always use the correct fastener in the proper location. When you replace a fastener, use ONLY the exact part number for that application. The manufacturer will call out those fasteners that require a replacement after removal. The manufacturer will also call out the fasteners that require thread lockers or thread sealant. UNLESS OTHERWISE SPECIFIED, do not use supplemental coatings (paints, greases, or other corrosion inhibitors) on threaded fasteners or fastener joint interfaces. Generally, such coatings adversely affect the fastener torque and joint clamping force, and may damage the fastener. When you install fasteners, use the correct tightening sequence and specifications. Following these instructions can help you avoid damage to parts and systems.

1. Install the bolts (8) to the wheel cylinder.
^ Tighten the wheel cylinder bolts to 20 Nm (15 ft. lbs.).






2. Install the backing plate (1) to the axle assembly.
3. Install the hub and bearing assembly with bolts. Refer to Wheel Hub and Bearing Replacement.
4. Install the parking brake cable to the backing plate.
5. Install the inlet tube.
^ Tighten the tube nut to 23 Nm (17 ft. lbs.).

6. Install the brake components. Refer to Brake Drum Replacement.

CAUTION: When servicing brake parts, do not create dust by grinding or sanding brake linings, by cleaning brake parts with a dry brush or with compressed air. Many earlier models or aftermarket brake parts may contain asbestos fibers which can become airborne If dust Is created during servicing. Breathing dust containing asbestos fibers may cause serious bodily harm. A water dampened cloth or water based solution should be used to remove any dust on brake parts. Equipment Is commercially available to perform this washing function. These wet methods will prevent fibers from becoming airborne.

7. Bleed the brake system. Refer to Hydraulic Brake System Bleeding
8. Lower the vehicle.
