Abstract
A load conscious control valve arrangement for modifying the pressure applied to the rear hydraulic brake of a motor cycle comprises a control valve rigidly mounted by a bracket on the frame of the motor cycle. The stem of the control valve is connected by a tension spring to an adjustable spring support of a combined spring/damper suspension strut. Deflection of the rear suspension as a result of increased loading causes an increased tension to be applied by the spring and thereby increases rear brake pressure. To compensate against the decrease in tension which would otherwise be applied to the valve stem when the adjustable stop is adjusted but there is no increase in the load on the motor cycle, an eccentric formed on the adjustable stop so that rotation of the stop may be provided to adjust the suspension strut causes a shift in the radial direction of the suspension strut of the point Z at which the spring is connected to the spring support.
