Compact drum brake adjuster

摘要

An automatic adjusting mechanism for a drum-type brake including a pair of slidably supported tappets for actuating the brake. The tappets are comprised of two threadably connected components which effect adjustment for wear upon relative rotation of the components. An interconnecting shaft insures simultaneous rotation of the respective components of the pair and an automatic adjusting device including an over-adjustment preventing mechanism operates on an extension of this interconnecting shaft.
