Abstract: A vehicle anti-skid brake control mechanism consisting solely of mechanical components, particularly for use in two-wheel vehicles comprising a first brake device for primarily absorbing vehicle travelling energy and a second brake device for secondarily absorbing a vehicle travelling energy when the braking force applied by the first brake exceeds a critical level of the braking force corresponding to wheel speeds. The apparatus further comprises a rotation overdrive device adapted to overdrive a rotative inertial body and centrifugal weights in the same direction as that of a wheel hub so as to minimize the shock produced when the braking force transmission means is actuated. A sliding rod is provided with an outer end portion thereof outwardly extended from the axle shaft and has marks indented thereon to visibly sense wear of clutch plates.
