Removal

WARNING: Although factory installed brake linings are made from asbestos free materials, some after market brake lining may contain asbestos. This should be taken into account when servicing a vehicle's brake system, when after market brake linings may have been installed on the vehicle. always wear a respirator when cleaning brake components as asbestos can cause serious bodily harm such as asbestosis and or cancer. Never clean brake components by using compressed air, use only a vacuum cleaner specifically designed for the removal of brake dust. If a vacuum cleaner is not available, clean brake parts using only water dampened shop towels. Do not create brake lining dust by sanding brake linings when servicing a vehicle. Dispose of all dust and dirt suspected of containing asbestos fibers using only sealed airtight bags or containers. Follow all recommended safety practices prescribed by the Occupational Safety And Health Administration (OSHA) and the Environmental Protection Agency (EPA), for handling and disposal of products containing asbestos.

During service procedures, grease or any other foreign material must be kept off brake shoe assemblies, and braking surfaces of brake drum and external surfaces of hub/bearing assembly.

Drum Brake Assembly:

The original equipment rear drum brake assemblies used on this vehicle are supplied by Varga N.A. Inc.

1. Raise vehicle on jackstands or centered on a hoist.
2. Remove the rear wheel and tire assemblies from the vehicle.

NOTE: If the vehicle has high mileage, the brake drums may have a ridge worn in them by the brake shoes. This ridge causes the brake drum to interfere with the brake shoes, not allowing the brake drum to be removed. Further clearance can be obtained by fully backing off the brakes automatic self adjuster mechanism, using the following procedure.





3. Remove the rubber plug from the top of brake support plate.





4. Insert a screwdriver, through the automatic adjuster access hole, in the rear brake support plate. Engage screwdriver with the teeth on the adjuster mechanism quadrant. Then rotate quadrant so that teeth on quadrant, are moved toward the front of the vehicle. Continue moving quadrant toward front of vehicle until it stops moving. This will fully back off the adjustment of the rear brake shoes allowing brake drum to be removed.





5. Remove rear brake drum to hub/bearing retaining nuts (if equipped). Then remove rear brake drum from hub and bearing assembly.





6. Remove the actuating spring from the automatic adjuster mechanism and the trailing brake shoe.





7. Remove the upper return spring from the leading and trailing brake shoe assembly.





8. Remove the lower return spring from the leading and trailing brake shoe assembly.





9. Remove the brake shoe retainer and pin from the leading brake shoe assembly.





10. Remove the leading brake shoe and the adjuster mechanism as an assembly, from the rear brake support plate. The adjuster mechanism can not be separated from the leading brake shoe until the brake shoe and adjuster mechanism is removed from the support plate.





11. Remove the brake shoe retainer and pin, from the trailing brake shoe.
12. Remove the trailing brake shoe assembly from the brake support plate.

CAUTION: On this vehicle, the park brake actuating lever is permanently attached to the trailing brake shoe assembly. Do not attempt to remove it from the original brake shoe assembly or reuse the original actuating lever on a replacement brake shoe assembly. All replacement brake shoe assemblies for this vehicle must have the actuating lever as part of the trailing brake shoe assembly.





13. Remove the park brake cable from the park brake actuating lever, attached to the trailing brake shoe assembly. Do not attempt to remove actuating lever from brake shoe assembly.





14. Remove the automatic adjuster mechanism from the original leading brake shoe assembly for installation on the replacement brake shoe, using the following procedure. Fully extend the adjuster mechanism in the direction shown. Then, with adjuster mechanism fully extended, rotate the adjuster mechanism in the direction shown to separate adjuster mechanism from leading brake shoe.
