ABSTRACT:
A method for fabricating a brake disc assembly comprising the steps of machining a radially extending gage surface (54) on the support flange (34) of an outer race (32) of a bearing assembly disposed around a hub (14) and inserting a fixture post (72) through a bore (22) in the hub (14). A pressure plate (74) presents tabs (90) simulating a vehicle wheel and is disposed in engagement with the base (26) of the brake disc with a washer
ut (78) over the pressure plate (74) to place the post (72) in tension against the bearing assembly to maintain a pre-load on the bearing assembly. The outer race (32) of the bearing assembly is clamped with the gage surface (54) drawn against a gage (84) to properly orient the outer race (32) about a fixed axis (A). Thereafter, the pressure plate (74) is engaged by a rotation member (86) which rotates about a floating axis (B). A resilient pad (68) is sandwiched between the pressure plate (74) and the rotating member (86) in a plane perpendicular to the rotation axis (B) as the rotating member (86) is urged against the pressure plate (74) to compress the resilient pad (68) between the rotating member (86) and the pressure plate (74). The braking surfaces (30) of the rotor (28) are machined (92) while the rotating member (86) rotates the hub (14) and brake disc relative to the outer race (32), which is held in a fixed position relative to the machining tools (92).
