ABSTRACT:
The invention is directed to a method for manufacturing a brake shoe particularly for drum brakes of motor vehicles, having a carrier of the brake lining whose outside surface has the shape of a circular cylindrical section, and having an arcuate or sickle-shaped web arranged radially inwardly of the carrier of the brake lining and by which the actuation forces of the brake are transmitted onto the carrier of the brake lining. The new manufacturing method provides that a ring having a cylindrical outside surface and a T-shaped cross section is shaped from a blank by buckling and subsequent flattening or by cleaving and subsequent flattening. The ring is divided into two or more ring segments each of which forms a brake shoe.
