Abstract
A spring for applying a biasing force to a disc of a brake hub assembly including a hub having a circumferential groove, at least one disc, and a plurality of guide pins for rotatably coupling the hub and the disc wherein the spring comprises a band for circumferentially engaging the hub. The spring is characterized by a plurality of axial position retention tabs circumferentially spaced and extending radially inwardly from the band for engaging the circumferential groove of the hub and for preventing axial movement between the spring and the hub. The spring is further characterized by a plurality of circumferential position tabs circumferentially spaced and extending radially outwardly from the band and being generally U-shaped and defining a guide pin opening for at least partially engaging one of the guide pins for rotatably coupling the spring and the hub.
