Brake Shoe: Adjustments
The rear drum brakes, have self-adjusting shoe mechanisms that assure correct lining-to-drum clearances at all times. The automatic adjusters operate
only when the brakes are applied as the vehicle is moving rearward. Although the brakes are self-adjusting, an initial adjustment is necessary after the
brake shoes have been replaced, or when the length of the star wheel adjuster has been changed during some other service operation.
