Abstract:
A brake shoe for a disk brake assembly for a vehicle wheel on a vehicle wherein the disk brake assembly includes a housing having an annular radial wall mounted to the vehicle, an annular rotor disk within the housing and co-axially mounted to the wheel, and an annular expandable bladder attached to the annular radial wall of the housing, the brake shoe comprising:a) a radial section parallel to the rotor disk; b) means associated with the housing for radially supporting the brake shoe within the housing; c) means associated with the housing for preventing the brake shoe from rotation so that upon expansion of the bladder during a brake action, the brake shoe moves towards the rotor disk resulting in frictional engagement between the rotor disk and the radial section of the brake shoe; and d) the radial section being made from a thin resilient metal material whereby during the brake action the brake shoe is deformable under uneven and variable forces resulting from imperfect machining or uneven wearing of the rotor disk.
