<p>A vehicle wheel brake system (9) for a wheel suspension assembly has an anti-lock braking system ('ABS') to provide a higher resolution brake apply and brake release relative to an ABS system having a single, fixed brake disc. The brake system comprises a mounting hub (14) for a road wheel mounted on the wheel suspension assembly for rotation about a rotational axis. At least two slidable brake discs (38, 41) are mounted to slide axially along the hub between braking and off-brake positions and provide signals when the wheel condition is within preset parameters relative to the speed of the vehicle. A brake actuator system is operable manually and is operable automatically by the ABS controller to operate the caliper and a frequency of brake apply and with release of at least double the frequency of brake apply and release of a fixedsingle brake disc system.</p> |
