1. A method for fabricating a brake disc assembly including a hub (14) extending between a drive end (16) and a wheel end (18) and presenting a disc flange (20) and having a bore (22) extending between the ends for receiving a drive shaft, a brake disc having a base (26) attached to the disc flange (20) and a rotor (28) extending radially from the hub (14) and presenting parallel braking surfaces (30), a bearing assembly surrounding the hub (14) between the drive end (16) and the disc flange (20) for supporting the hub (14) with an outer race (32) presenting a support flange (34) for attachment to a support structure (36), said method comprising the steps of:

  • clamping the outer race (32) of the bearing assembly in a fixed orientation about a fixed axis;

    rotating the brake disc about a floating axis to allow for relative radial movement between the brake disc and the outer race (32); and

    machining the braking surfaces (30) of the rotor (28) while rotating the hub (14) and brake disc relative to the outer race (32).
