Claim:
1. A brake hub assembly comprising: a brake hub defining a central axis and including an interior recess defining a bearing seat in which at least a portion of a wheel bearing is received; a brake disk coupled to the brake hub, the brake disk having: a first plate; a second plate spaced axially from the first plate; and a plurality of ribs extending between the first and second plates to define a plurality of cooling channels therebetween, each channel having an opening with an inboard edge, the first plate being inboard from the second plate and the second plate having a braking surface, a thickness defined between the braking surface and one of the cooling channels, and a plurality of radially extending slots through the thickness of the second plate, the second plate being annular and having a plurality of pilot surfaces in direct contact with the brake hub and alternating with the radially extending slots in a circumferential direction about the central axis, the pilot surfaces defining an inner diameter of the second plate; a torque member extending from the brake hub and received in one of the radially extending slots of the brake disk, the torque member having an inboard end with a threaded bore therein, wherein the inboard end does not extend axially beyond the inboard edge of the opening; an axial preload spring for biasing the brake disk towards an axial qualifying surface of the torque member; and a fastener received within the threaded bore, and extending through the same radial slot in the brake disk in which the torque member is received, for clamping the axial preload spring to the torque member.
