<p>A drum brake assembly includes a brake member (2) comprised of a substantially circular shoe (5) having a radially outer face (8) on which at least one lining (6, 7) is mounted. The shoe (5) is made from a high strength resilient material and is of substantially constant cross-section along its entire length. The brake member (2) is arranged to be diametrically expanded by actuation means (9) on the brake assembly. When the actuation means (9) is released, the resilience of the shoe material causes the shoe (5) to diametrically contract. The lining (6, 7) may be machined to a circular form prior to the brake member (2) being fitted to the brake assembly, and that machining is preferably done after the shoe (5) has been expanded a predetermined extent. <IMAGE></p> |
