A disc brake system comprises a mounting hub and at least one disc supported by the mounting hub. The mounting hub has a center portion and an outer portion substantially perpendicular to the center portion and defines a central axis extending perpendicular to the center portion. A plurality of grooves are defined within the outer portion and are spaced radially about the central axis. Each of the grooves extends longitudinally relative to the central axis. A bearing is disposed in each of the plurality of grooves and operatively connects the mounting hub and the disc such that the bearing rotates about a bearing axis and moves longitudinally within the groove in response to axial movement of the disc.
