The disc has a central part (16) and a peripheral part divided into spokes (17) which take the friction lining. Each spoke is connected to the central part by a foot (80,81) and has a central carrying zone (21A,21B) parallel to the plane of the central part for attachment of the friction lining.. To form a tripod certain spokes have a central carrying zone (21A,23B) and two peripheral carrying zones (21B,23A) either side the central zone. The central zone is connected to the disc central part (16) by a tangential foot (80,81) perpendicular to the radial axis of symmetry of the spoke and to the peripheral zones (21A,23B) by sloping feet (22A,22B). |
