ABSTRACT:
An internal shoe drum brake incorporates an automatic adjuster which includes and adjuster element carried by one of the brake shoes, a strut extending between the shoes and engaged by the adjuster element and a rotary adjuster cam mounted on the same shoe as the adjuster element, or a parking brake lever pivoted on the shoe, the cam engaging the adjuster element in a non-rotatable manner. When the shoes are separated for braking, excess shoe separation causes the adjuster element to be disengaged from the cam so that the cam is rotated by a spring to re-engage the adjuster element and thereby establish a retracted position of the shoes.
