ABSTRACT:
A self-balancing structure for brake shoes in a caliper brake assembly to equalize essentially wear of brake linings. Brake assembly has frame journalling on opposite sides thereof opposed first and second arms, the arms journalling first and second brake shoes respectively. The arms cooperate with brake actuator, and member to be braked is positioned between the shoes. Self-balancing structure includes pair of balancing links, each link interconnecting a particular shoe on one side of frame with an arm on opposite side of frame so that each shoe reflects movement of opposite arm. Thus a movement towards the member by one side of the shoe is reflected by movement of essentially equal magnitude towards member by an opposite side of the other shoe. Resilient connector can be provided in balancing link to accommodate lateral movement of the member, thus permitting brake shoes to float to an extent determined by resilient connector.
