Title: Brake assembly

Abstract: A brake assembly including a pair of brake shoes having adjacent ends pivotally mounted to a support and an actuator disposed between the ends of the brake shoes. The brake shoe webs are recessed at one end to engage a fixed anchor pin. The recess provides an arcuate bearing surface adapted to bear against a portion of the pin and permit pivoting movement of the brake shoe about the pin as the brake is actuated and released. The recess is also so oriented relative to the pin that the recess abuts the pin and prevents the brake shoe from moving away from the anchor pin. The brake assembly also includes an anchor pin having axially spaced cylindrical bearing areas adapted to radially, slidably receive the open ended recesses of a dual web brake shoe and a pair of oppositely facing surfaces extending radially outward at axially spaced locations on the pin to abut the brake shoe webs and prevent the anchor pin from being axially displaced from the support.
