ABSTRACT:
The present invention relates to a brake shoe and brake assembly for automotive vehicles, comprising a pair of brake shoes (14) having ends pivotably mounted on a brake spider (12), and a actuator cam (26) located between the opposite ends of the brake shoes (14). The webs (24) of brake shoes (14) have adequate apertures in the pivoting ends, to engage rotational anchor pins (16). The apertures have radial sections and lateral flats to engage radial sections and lateral flats in the ends of the anchor pins (16). The apertures form slidable, but not rotational, connections with anchor pins (16), to support brake shoes (14), and allow a pivoting movement of brake shoes (14), through anchor pins (16), when an application and release of the brake is effected. The aperture is directed in such a way in respect to a line that passes through the centers of the brake assembly and of the rotational pin (16), that the end of the brake shoe forms a hook preventing the end of the shoe, having the aperture from being moved away from the anchor pin (16), whenever a brake application is effected.
