  • Axial retention of the shoe of a drum brake and a drum-brake shoe equipped with an axial-retention device
    Patent number: 4553649
    Abstract: A drum brake assembly includes a pair of brake shoes which are slidably mounted on a fixed support. An elastic retention member is mounted on each of the shoes before they are assembled onto the fixed support. Each of the retention members includes a locking portion which engages the web of the brake shoes, and a pair of arm portions which extend from the locking portions and which engage the web of the brake shoe in such a way as to releasably maintain the locking portion engaged with the web of the brake shoe. When the brake shoes are assembled on the torque member, a portion of the torque member is provided with a sloped edge that engages the locking portion to release the latter as the brake shoes are assembled onto the fixed support, so that the retaining member then exerts a biasing force between the torque member and the brake shoes.
