Ford Bronco Rear Drum Brake Diagram - Shoes, Springs & Self-Adjuster Layout

This document is a labeled cutaway diagram of a drum brake assembly, identifying the major components and their positions within the brake drum. Callouts identify the anchor pin at the top, the secondary shoe return spring and primary shoe return spring, the wheel cylinder located between the tops of the two brake shoes, the secondary brake shoe (toward the rear) and primary brake shoe (toward the front, indicated by a 'FRONT' arrow), two retaining springs, the backing plate, the self-adjuster at the bottom, and the brake drum itself. Two instructional notes are included: the secondary brake lining does more of the work of braking than the primary brake lining, and the primary brake lining is thinner, shorter, and sometimes made of a different material than the secondary brake shoe lining. The figure carries the reference number H9810-A. A reader can learn the names and locations of drum brake parts, which shoe faces forward, and why the primary and secondary shoe linings differ in size and material. The document contains no year, model, torque, or part-number information beyond the figure reference code; it was uploaded as a reference for a 1992 Ford Bronco.
