Warning

•  When removing/installing the brake drum component parts, the spring could fly off and cause injury. Remove/install the spring being careful not to allow the spring to fly off. Wear protective equipment such as safety glasses if necessary.

Caution

•  The parts securing the parking brake cable may be damaged if the parking brake lever is pulled while the brake drum is removed. Operate the parking brake lever only when the brake drums are installed.

Note

•  Excessive clearance between the brake drum and brake shoe could affect the correct operation of the automatic adjuster function. If the brake drum or brake shoe has been removed, verify that the clearance is within the specification and adjust it by turning the adjust screw of the adjuster using a flathead screwdriver if necessary.
