Brake Systems - DELCO-Moraine Automatic Adjuster: Description

Hydraulic single anchor type brake with Bendix type shoes. Brake shoe anchor pins are fixed in backing plate and require no adjustment. Automatic adjusting mechanism consists of a link, actuating lever, pawl and pawl spring (mounted on secondary brake shoe). System also contains an override pivot plate and spring, which acts to protect against binding linkage.

NOTE: Some models use an adjuster pawl having a separate blade to contact adjuster star wheel. Use of this design eliminates override spring.
