The systems and methods of automatically cleaning a wheel are disclosed herein. The systems and methods include a foreign matter detector arranged adjacent to the wheel, a cleaning device arranged adjacent to the wheel, one or more processors communicatively coupled to the foreign matter detector and the cleaning device; and a non-transitory, processor-readable storage medium communicatively coupled to the one or more processors. The non-transitory, processor-readable storage medium includes one or more programming instructions stored thereon that, when executed, cause the one or more processors to: receive a signal from the foreign matter detector, the signal being indicative of possible foreign matter present on a surface of the wheel, determine from the signal, whether foreign matter is present on the wheel, and direct the cleaning device to remove the foreign matter from the wheel.

A brake assembly for a wheel on a vehicle includes a brake disc, a caliper assembly operably coupled to the brake disc, a brake line fluidly coupled to the caliper assembly, and a brake shield positioned adjacent a portion of the caliper assembly. The brake shield includes a first arm positioned on a first side of a portion of the brake disc and a second arm positioned on a second side of the portion of the brake disc. The brake disc further includes a recess configured to receive a portion of the brake line.

According to an embodiment, a carrier with retractable wheels comprises a main body including a storage space and an inlet hole formed in a bottom to be open or closed by a sliding plate and a moving unit having a body pivotably provided in the inlet hole and a wheel attached to an end of the body. When the inlet hole is closed by the sliding plate, the moving unit is pivoted up, the wheel is supported by the sliding plate to be positioned inside the inlet hole and, when the inlet hole is open, the moving unit is pivoted down to stick out of the inlet hole.
