ABSTRACT:
Integrally formed brake shoe for use with cylindrical automotive brake drums in hydraulic brake systems are fabricated by bending and shaping sections of extruded lengths of the material having a T-shaped cross-sectional configuration. Connector pins for transmitting brake actuating forces between the hydraulic cylinder pistons and the brake shoes are concavely rounded at their piston abutting ends, and either concavely or convexly rounded at their brake shoe abutting ends, for face-to-face sliding contact with complemental abutting surface portions, respectively, of the hydraulic pistons and brake shoes.
