Abstract
A drum brake adjuster having a spring biased lock plate cooperating with a parking brake strut having a lost motion connection with a parking brake lever. The lost motion determines the amount of shoe retraction, and the lock plate adjusts the effective length of the strut for brake shoe wear. The lock plate and its spring are mounted on one shoe web near one end of the strut, with the other strut end being connected to the parking brake lever.
