Brake Systems - DELCO-Moraine Automatic Adjuster: Description
Hydraulic single anchor type brake (without eccentric) 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 return spring (mounted on secondary brake shoe).
