Abstract
A brake slack adjuster includes a housing defining a pair of intersecting bores therein. A gear is rotatably mounted in one of the bores, and is splined to a cam shaft which mounts a cam brake actuator. A worm shaft is mounted in the other bore and a worm is rotatable with the worm shaft to turn the gear. The worm shaft is supported in the bore by a surface tapering toward the open end of the bore that cooperates with a retaining ring which is received in a circumferentially extending groove circumscribing the bore to retain the worm gear in the bore. The retaining ring terminates in an arm which tapers toward the open end of the bore and engages flats provided on the worm shaft which are adapted to receive a conventional mechanic's socket to turn the shaft when the brake is to be adjusted. The arm yieldably locks the shaft against rotation, to prevent the adjustment from backing off after it is made.
