Abstract

A self-contained drum brake adjuster mechanism using an escapement drive arrangement to provide adjustment. A bi-metal spring, used in the normal adjustment operation, contracts at higher brake temperatures to prevent over-adjustment of the brake when the drum is overly expanded due to heat generated by heavy brake applications.
