Drum Brake - Conventional Design
Delco single anchor, duo-servo type brake assemblies are used on the rear of all models except light duty "C" Series. The assemblies consist of a support plate, 2 brake shoes, return springs, automatic adjuster components and a duo-servo wheel cylinder.
Automatic adjusters consist of a connecting link, override lever, override spring, return spring, actuating lever and an adjusting screw. Normal adjustment is accomplished through movement of actuating lever and secondary shoe during application of brakes when vehicle is operated in reverse.
