  • Patent number: 6345708
    Abstract: It is one object of this invention to eliminate a driver's impression of delay in braking effectiveness at an initial stage of a braking operation and the phenomenon of over-braking with an internal drum brake device. For this purpose rigid anchor members (61b, 61b) and deformable anchor members (64, 64) respectively providing supporting points for the brake shoes are located at diametrically different positions from a brake center. The brake shoes (20, 30) are supported by the deformable anchor members (64, 64) until a braking force reaches a predetermined value but are supported by the rigid anchor members (61b, 61b) when braking forces exceeds the predetermined value.
