Abstract
Abstract A disc adapter for attaching rotatable discs of a disc brake system to a wheel is modified to include an exciter ring of a sensor unit of an anti-skid system used in conjunction with the braking system. The exciter ring is oriented co-axially with the wheel and contains a plurality of equally and annularly spaced ripples. Rotational movement of the exciter ring and the wheel is detected by a stationary magnetic pickup device adjacent to the exciter ring.
