Abstract
A slack adjuster assembly for brakes includes a slack arm, ratchet wheel and pawl carrier all rotatable about a common axis in unison and relative to one another. The parts rotate in unison during normal operation when the slack arm rotates back and forth in brake apply and brake release directions. When an adjustment is required due to brake wear, the slack arm will overtravel in the brake apply direction. When overtravel occurs, rotation of the pawl carrier with the slack arm and ratchet wheel through the overtravel portion of the stroke is stopped to effect relative rotation between the pawl carrier and the ratchet wheel. Upon return of the slack arm in the brake release direction from an overtravel stroke, the pawl carrier is rotated relative to the slack arm and rotatably drives the ratchet wheel relative to the slack arm.
