A disc brake assembly (10) has a housing (12) mounted to a vehicle and two rotor discs mounted to a wheel of the vehicle. Three annular brake shoes (30,54,76) are operatively supported by the housing (12) and a support structure of the vehicle, respectively. Rotor discs and two of the annular brake shoes are adapted to move axially towards an axially restrained brake shoe for frictional engagement with one another during a brake action. The housing (12) includes an annular radial wall (14) and a plurality of axial link members (16) circumferentially spaced apart from one another. The link members (16) are secured to the support structure of the vehicle using mounting screws (102) received in mounting bores (100) thereof. Each mounting bore (100) extends radially through an elongated key (98) and is offset from the center of the key. The elongated key (98) is adapted to be inserted in opposite orientations in an elongated aperture defined in the distal end of the axial link member (16) of the housing (12) so that the axial position of the mounting bores (100) is selected. The simple structure of the housing (12) provides an adjustment feature to reduce the travel distance of moving parts to compensate for wear. This wear compensation solution is reliable and inexpensive.
