Brake Shoes, Rear

The Brake Shoe replacement starts with vehicle support and continues with tire removal and Brake Drum separation before moving on to brake adjuster components. The adjuster spring along with the adjuster actuator lever needs to be removed from the pivot point. Insert the j 38400 Brake Shoe spanner and spring remover (J 38400) between the Brake Shoe tops to spread them before you extract the adjuster assembly from between its open ends. The j 38400 hook end tool should be placed beneath the universal spring so you can remove the shoe web hole but the universal spring must be firmly held with the tool for Brake Shoe removal. An operator should release the park brake cable from the park brake lever then use the j 38400 to remove the second Brake Shoe. Brake installation requires thin application of high-temperature silicone brake lubricant on both right and left brake backing plates contact surfaces. The proper installation of the trailing shoe requires the j 38400 to position the universal spring into the Brake Shoe web hole. Follow the installation of park brake cable to lever by using the j 38400 to spread brake shoes and install the adjuster assembly. The adjuster assembly requires installation of the adjuster spring after reattaching the adjuster actuator lever while the drum brake system adjustment takes place followed by drum brake assembly and tire reinstallation as well as wheel assembly before lowering the vehicle.

Begin Brake Shoe replacement by lifting the vehicle and implementing support while taking off the tire and wheel followed by the Brake Drum. Take the adjuster spring and adjuster actuator lever out from the pivot unit. Install the j 38400 (J 38400) Brake Shoe spanner and spring remover to open the brake shoes on top while taking away the adjuster assembly. Insert the hook end of the j 38400 into the universal spring underneath the shoe web hole then pull it slowly while maintaining universal spring contact by using the tool to remove the Brake Shoe. Follow the same steps to remove the other Brake Shoe after pulling the park brake cable out from its connection with the park brake lever. When installing the backing plates use high-temperature silicone brake lubricant for a thin application between their contact surfaces. Installation of the trailing Brake Shoe requires the j 38400 tool to enable proper engagement of the Brake Shoe web hole with the universal spring. Proceed with installing the park brake cable to the park brake lever and apply the j 38400 tool to spread the top of the brake shoes before inserting the adjuster assembly and adjuster actuator lever and adjuster spring. Complete the procedure by adjusting the drum brake system before application of Brake Drum and tire and wheel assembly to lower the vehicle.
