ABSTRACT:
This invention relates to a braking apparatus wherein the heat absorbing mass of a rotating braked element, such as a vehicle wheel, is increased by securing to such as each wheel of a vehicle, a brake drum, the peripheries of the wheels and drums constituting braking surfaces against which a plurality of brake shoes are pressed during a brake application by a movable member between which and each pair of the plurality of brake shoes there is interposed an equalizer lever that is pivoted intermediate its ends on the movable member, each equalizer lever being thereby rockable relative to the movable member to enable each one of the corresponding pair of brake shoes to transmit substantially the same braking force to the braking surface braked thereby notwithstanding the rate of wear of either one of any pair of brake shoes exceeding that of the other brake shoes.
