Brake Shoes, Rear

Start by raising and supporting the vehicle before removing the tire along with its wheel along with the Brake Drum itself. Work carefully to prevent stretching the adjuster spring since it could lead to structural damage. The Brake Shoe web hole needs a hook end adjuster spring release to free it from its position before it can be removed. You should now take out the adjuster actuator lever from its position on the pivot. The operations must be carried out with j 38400 Brake Shoe spanner and spring remover while pulling up the top of brake shoes to extract the adjuster assembly. Pull the hook end of the j 38400 under the universal spring through the shoe web hole but hold it while doing so before extracting the trailing Brake Shoe. Moving forward with the work, free the park brake cable at the park brake lever on the trailing shoe and follow the same steps on the leading Brake Shoe. Test the Brake Shoe lining thickness which must exceed 0.5 mm (0.020 in) before moving forward; otherwise replace the brake shoes. A small amount of silicone high-temperature brake lubricant should be applied to the Brake Shoe contact surfaces on the backing plate. Use the hook of j 38400 to insert the universal spring beneath the leading Brake Shoe web hole until it properly connects. First reinstall the park brake cable to the park brake lever which is located on the trailing Brake Shoe before installing this shoe the same way. Place the j 38400 under the brake shoes to separate them once more and complete installation of both the adjuster assembly and the adjuster actuator lever with correct connection. Sew the adjuster spring into position by letting its loop segment reach the actuator lever tab completely. The last step is to set the drum brakes before installing the Brake Drum followed by tire and wheel assembly plus lowering the vehicle.

Measure the brake shoe lining thickness, ensuring it is at least 0.5 mm (0.020 inch); if not, replace the brake shoes.

Reinstall the park brake cable to the park brake lever on the trailing brake shoe, then install the trailing brake shoe in the same manner.

Use the J 38400 to spread the top of the brake shoes apart again, then install the adjuster assembly and the adjuster actuator lever, ensuring proper engagement.

Release the park brake cable from the park brake lever on the trailing shoe.
