Abstract
An automatic clearance adjuster for a cam actuated vehicle brake. The adjuster is disposed in a pivotal lever and includes a worm and worm gear, an adjusting mechanism for effecting a clearance decreasing rotation of the worm during the brake apply stroke and a clearance increasing rotation of the worm during the brake release stroke, a two-way torque limiting ratchet clutch which slips to prevent rotation of the worm by the adjusting mechanism when the shoes are in contact with the drum, and a roller clutch which allows a predetermined amount of clearance increasing rotation of the worm by the adjusting mechanism during the brake release stroke and then locks up and causes slippage of the torque limiting clutch to prevent further clearance increasing rotation of the worm.
