Abstract

A drum brake is disclosed which includes an automatic adjustment mechanism which advances the brake released position of the brake shoes toward the drum to compensate for lining wear. A temperature responsive element prevents operation of the adjuster mechanism when the temperature of the brake exceeds a predetermined level, to prevent over adjustment of the brake.
