Inside a drum brake, the parking brake strut spans between the brake shoes. When the parking brake is applied, it helps carry the lever's force so the shoes are pushed out against the drum. This part is listed under two names, parking brake strut and drum brake bar lever. It is cataloged for both the rear left and rear right positions.
Signs this part may need replacing include a parking brake that holds poorly, extra lever or pedal travel, or a rattle from a rear drum. These symptoms can have other causes, so inspect the brake before replacing parts. Servicing both rear sides together is recommended for balanced parking brake operation.
