ABSTRACT:
A method for mounting a production rotor (20) to a hub (22) of a wheel assembly (10) for a vehicle. The rotor (20) comprises a disc (32) having braking surfaces (24, 26). The rotor (20) also has a central plate (28) that is offset from the disc (32) and rotor studholes (30) extending through the central plate (28). The hub (22) has a flange (34) and studs (36) for attaching the hub (22) to the rotor (20). The method comprises the steps of clamping the central plate (28) of the production rotor (20) to a gage hub (122); and measuring the axial displacement (dt) of one of the braking surfaces (24, 26) from a free state plane (A). The production rotor (20) is marked to indicate the rotor position of one of the maximum and minimum displacement (dt) thereof. Also included are the steps of clamping the production hub flange (34) to a gage rotor (120) having gage braking surfaces (124, 126); and measuring the axial displacement (dh) of the gage braking surface (124, 126) from a free state plane (B). The production hub flange (34) is marked at a hub position radially aligned with one of the maximum and minimum displacements (dh) of the gage braking surface (124, 126). Thereafter, the method is completed by angularly positioning the rotor and hub positions in a predetermined relationship to one another and assembling the production rotor (20) onto the production hubs (22) to thereby minimize runout.
