Abstract
A pair of arcuate brake shoes in a vehicle brake assembly are pivotably supported on a pivot pin which is directly mounted to a steering knuckle add activated by an S-cam type actuator where an S-cam actuator shaft is supported in a support tube which is attached directly to the steering knuckle thereby eliminating the traditional brake spider. Rotation of the S-cam causes a pair of cam followers to separate the brake shoes resulting in frictional contact between the brake shoes and a brake drum. Elimination of the brake spider to support the pivot pin and the S-cam actuator shaft housing reduces complexity for lower cost and improved performance.
