ADJUSTMENT
REMOVAL & INSTALLATION Details are as follows: ----


Adjustment



The drum brakes are self-adjusting and require a manual adjustment only after the brake shoes have been replaced, or when the length of the adjusting screw has been changed while performing some other service operation.
Drum Installed
  1. Raise and support the vehicle safely.
  2. Remove the rubber plug from the adjusting slot on the backing plate.
  3. Insert a Brake Adjustment Tool (D81L-1103-C) or equivalent into the slot and engage the lowest possible tooth on the starwheel. Move the end of the brake spoon downward to move the starwheel upward and expand the adjusting screw. Repeat this operation until the brakes lock the wheels.
  4. Insert a small screwdriver or piece of firm wire (coat hanger wire) into the adjusting slot and push the automatic adjusting lever out and free of the starwheel on the adjusting screw and hold it there.
  5. Engage the topmost tooth possible on the starwheel with the brake adjusting spoon. Move the end of the adjusting spoon upward to move the adjusting screw starwheel downward and contract the adjusting screw. Back off the adjusting screw starwheel until the wheel spins freely with a minimum of drag. Keep track of the number of turns that the starwheel is backed off, or the number of strokes taken with the brake adjusting spoon.
  6. Repeat this operation for the other side. When backing off the brakes on the other side, the starwheel adjuster must be backed off the same number of turns to prevent side-to-side brake pull.
  7. When the brakes are adjusted, make several stops while backing the vehicle to equalize the brakes on both of the wheels.
  8. Lower the vehicle.
Drum Removed
  1. Remove the brake drum.
  2. Make sure that the shoe-to-contact pad areas are clean and properly lubricated.
  3. Using a Brake Adjustment Gauge (D81L-1103-A) or equivalent, check the inside diameter of the drum.
  4. Measure across the diameter of the assembled brake shoes, at their widest point.
  5. Turn the adjusting screw so that the diameter of the shoes is 0.030 in. (0.76mm) less than the brake drum inner diameter.
  6. Install the drum.

Removal & Installation



  1. Raise and support the vehicle safely.
  2. Remove the brake drum.
    NOTE
    It is a good idea to only disassemble and assemble one side at a time, leaving the other side intact as a reference.
  3. Raise and support the vehicle safely.
  4. Remove the brake drum.
  5. Disconnect the parking brake rear cable and conduit.
  6. Remove the brake shoe hold-down springs and brake shoe hold-down pins.
  7. Remove the brake shoe adjusting screw spring.
  8. Remove the brake shoe adjusting lever and adjuster screw.
  9. Remove the brake shoe retracting spring.
  10. Remove the brake shoes from the backing plate.
  11. Remove and discard the parking brake lever clip. Remove the washer.
  12. Remove the parking brake lever from the rear brake shoe.

To install:
  1. Thoroughly clean the backing plate with brake cleaning solvent and dry completely.
  2. Use silicone grease to lubricate the brake backing plate-to-brake shoe contact areas.
  3. Apply a light coating of premium grease to the threaded areas of the adjuster. Turn the adjuster in and out to spread the lubricant. Turn the adjuster all the way down on the screw and loosen one-half turn.
  4. Install the parking brake lever to the rear (secondary) brake shoe with a new clip.
  5. Position the brake shoes on the backing plate and install the brake shoe hold-down springs.
  6. Attach the parking brake rear cable and conduit to the parking brake lever.
  7. Attach the brake shoe retracting spring.
    NOTE
    The socket end of the brake adjuster screw is stamped with -R- or -L- to indicate that it is to be installed either on the right (passenger-s side) or left (driver-s side) of the vehicle. The adjuster nuts can be distinguished by the number of grooves machined around the body of the nut. Two grooves indicate a right-hand adjuster nut and one groove indicates a left-hand adjuster nut. Another way to identify brake adjuster assemblies is to check thread pitch. The right side adjuster assembly has right-hand threads and the left side has left-hand threads. If installed correctly, the brake adjuster assembly will increase in length when the brake shoe adjusting lever is operated.
  8. Install brake adjuster screw in the slots on the brake shoes. The wider slot on the socket end must fit in the slot on the front (primary) brake shoe.
  9. Install the brake shoe adjusting lever on the lever pin.
  10. Install the brake adjusting screw in the slot on the secondary brake shoe and in the slot on the brake shoe lever. The brake shoe adjusting lever should contact the brake adjuster screw.
  11. Adjust the brake shoes.
  12. Install the drums.
  1. Raise and safely support the vehicle.
  2. Remove the wheel and tire assembly.
  3. Remove the brake drum.
  4. Disconnect the parking brake cable from the trailing brake shoe parking brake lever.

  5. Remove 2 brake shoe hold-down springs and pins.
  6. Remove the brake shoe adjusting screw spring (upper spring) and the brake shoe adjusting lever.
  7. Remove the brake shoe adjuster assembly.
  8. Remove the brake shoe retracting spring (lower spring).
  9. Remove the brake shoes from the backing plate.
  10. On the trailing shoe equipped with the parking brake lever, remove and discard the parking brake lever clip. Remove the washer and the parking brake lever.

To install:
  1. Inspect the brake drum for glazing, cracks, uneven wear or out of round. Machine or replace the brake drum as required. If machining, observe the maximum diameter specification.
  2. Inspect the wheel cylinder for leakage. Gently work the wheel cylinder pistons to make sure that they move without binding. Replace the wheel cylinder, as needed.
  3. Check the new brake shoes that they are correct for the application.
  4. Swap over or install new pins into the leading and trailing shoes for the parking brake lever and the brake shoe adjusting lever using the old shoes as a guide.
  5. Apply a high temperature grease to the backing plate/brake shoe contact areas.
  6. Apply a light coat of a high temperature grease on the threads of the adjuster nut and socket of the brake shoe adjuster assembly. Screw the adjuster nut and socket to its shortest position and then lengthen it 1 / 2 turn.
  7. Install the parking brake lever to the trailing shoe with the washer and a new parking brake lever clip.
  8. Position the trailing shoe onto the backing plate and install the brake shoe hold-down spring and pin.
  9. Position the leading shoe to the backing plate and install the brake shoe hold-down spring and pin.
  10. Attach the parking brake cable to the parking brake lever on the trailing brake shoe.
  11. Attach the brake shoe retracting spring (lower spring) between the brake shoes.
  12. Install the brake adjuster assembly in the slots between the brake shoes. The wider slot on the socket end must fit in the slot on the leading brake shoe. The slot on the adjuster nut end must fit in the slots on the trailing shoe and the parking brake lever.
    NOTE
    The socket end of each brake adjuster screw is marked with an R or L indicating the right or left side of the vehicle. The adjuster nuts can also be identified for which side they belong to by the number of grooves machined around the body of the adjuster nut. Two grooves indicate a right-hand adjuster nut (right-hand thread) while 1 groove indicates a left-hand adjuster nut (left-hand thread).
  13. Install the brake shoe adjusting lever on the adjusting lever pin.

  14. Install the brake shoe adjusting screw spring (upper spring) in the slot on the trailing shoe and in the slot on the brake shoe adjusting lever. Make sure that the brake shoe adjusting lever contacts the brake adjuster screw.
  15. Use a suitable brake adjustment gauge to measure the inside diameter of the brake drum.
  16. Adjust the brake shoes to match the inside diameter of the brake drum.
  17. Slide the brake drum onto the hub. Make sure that the brake shoes are not tight to the brake drum.
  18. Install the wheel and tire assembly. Torque the lug nuts to 85-105 ft. lbs. (115-142 Nm).
  19. Lower the vehicle.
  20. Check and fill the brake master cylinder, as required.
  21. Road-test the vehicle and check for proper brake operation.

This details will help.
