Abstract

An adapter of a brake system includes a body that extends around a portion of an axle of a vehicle system. The body may include an interior portion that is positioned between a center passage of the body and an exterior portion of the body in a radial direction away from the center passage. A hub coupling feature is positioned on the interior portion of the body and may be coupled with a portion of a wheel hub of the vehicle system. A brake disc coupling feature is positioned on the exterior portion of the body and may be coupled with a portion of a brake disc assembly. The wheel hub and the brake disc assembly are incompatible such that the wheel hub is prohibited from being directly coupled with the brake disc assembly.
