Abstract
A drum brake assembly including a brake member comprised of a substantially circular shoe having a radially outer face on which at least one lining is mounted. The shoe is made from a high strength resilient material and is of substantially constant cross-section along its entire length. The brake member is arranged to be diametrically expanded by an actuation device on the brake assembly. When the actuation device is released the resilience of the shoe material causes the shoe to diametrically contract. The lining may be machined to a circular form prior to the brake member being fitted to the brake assembly, and that machining is preferably done after the shoe has been expanded a predetermined extent. The disclosure extends to a method of manufacturing a brake member and to a brake member for a drum brake assembly.
