Abstract
A self-energizing disc brake shoe assembly for vehicles. It comprises a pair of relatively slidable and tapered blocks, each containing return springs surrounding rigid stems mounted in recesses of the blocks. One block serves as the backing plate and the other, as a self-energizing brake shoe. When the two blocks and a brake lining mounted on the brake shoe, engage the disc of a brake, the blocks move relatively apart longitudinally against a wedging action which affects progressive braking on the disc brake shoe. Upon release of the brake, the two blocks, by virtue of their return springs, will return to a neutral position, that is, with the blocks nested together.
