Abstract: A drum brake assembly and a drum having an annular drum wall with an open end and an attachment end. The drum wall further includes an outer drum surface and an inner braking surface, each of which extends between the open end and the attachment end. The drum includes a hub attachment section which is attachable to an associated wheel hub. The drum also has a drum wall connection section extending between the attachment end of the drum wall and the hub attachment section, where the drum wall connection section comprises a plurality of radially angled vanes interspersed with a corresponding plurality of air openings.

Abstract: A system for retaining a back plate of a disc brake pad is described. The system includes an elongated resilient element for applying a force to the back plate, a base of the resilient element extending along an edge of the back plate, contacting the edge along a majority of its length, legs of the resilient element, extending from the base, generating the force applied to the back plate by the base when deformed by a compression element, and retaining elements for preventing axial displacement of ends of the resilient element, and lateral slipping of the resilient element.
