1. A wheel end assembly comprising:
a brake rotor comprising:
a support disk having an annular configuration and configured for connection to a wheel for rotation with the wheel about a rotation axis; and
a first friction pad portion and a second friction pad portion each having annular configurations and connected to opposing sides of the support disk, wherein the first friction pad portion and the second friction pad portion comprise a brake friction material;
a caliper assembly that is configured for connection to a hub retainer that supports the wheel and configured to move radially with respect to the rotation axis, wherein the caliper assembly is configured to engage the first friction pad portion and the second friction pad portion of the brake rotor to inhibit rotation of the brake rotor and the wheel relative to the hub retainer;
a damper assembly that is configured for connection to the hub retainer and is connected to the caliper assembly, with the damper assembly configured to regulate movement of the caliper assembly with respect to the hub retainer, wherein the caliper assembly and the damper assembly cooperate to define a mass damper system that is configured to damp vibration of the wheel; and
a linear bearing, with the caliper assembly configured for connection to the hub retainer by the linear bearing, wherein the linear bearing is configured to restrain movement of the caliper assembly according to a line of action.
