Drum Brake Diagram - Wheel Cylinder, Brake Shoes & Star Adjusting Screw

This document is a labeled schematic illustration of a drum brake assembly, uploaded to the gallery of a 1977 Chevrolet Corvette. The drawing shows a rear view of the complete drum brake with the drum removed, exposing the internal components mounted on the backing plate. Three components are explicitly labeled with leader lines: the Wheel Cylinder at the top of the assembly, the Star Adjusting Screw at the bottom, and the Brake Shoes on the right side. The illustration also depicts (though does not label) return springs, hold-down hardware, and the adjuster mechanism connecting the two shoes. A reader can learn the general layout of a drum brake — where the wheel cylinder sits relative to the shoes, how the shoes are arranged around the backing plate, and where the star adjusting screw for shoe adjustment is located. The document carries no year, make, model, or part number information of its own; it appears to be a generic reference illustration from an automotive manual or catalog. It would be useful as a quick visual identification aid when servicing, adjusting, or diagnosing drum brakes.
