1. A vehicle, comprising:
a hub retainer configured to rotatably support a wheel along an axis;
a brake configured to decelerate rotation of the wheel, the brake comprising:
a rotor configured to rotate about the axis, with the rotor configured to be mounted to the wheel, and
a caliper mounted to the hub retainer and configured to selectively contact the rotor and induce friction therebetween to decelerate the rotation of the rotor and the wheel; and
a damper mass configured to move relative to the hub retainer to counteract vibrations produced by movement of the wheel against a travel surface, with the damper mass comprising:
an external surface configured to face toward the rotor with at least a portion of the external surface tapered to direct debris away from the axis and out from between the damper mass and the rotor;
a first leg and a second leg disposed on opposing sides of the axis; and
a body extending between the first leg and the second leg, with the first leg, the second leg, and the body defining a channel through which the axis extends,
wherein the caliper of the brake is positioned above the axis and the channel of the damper mass, with the channel configured to permit movement of the damper mass relative to the caliper.
