Abstract
A brake apply system having both a mechanical system and a hydraulic system. The hydraulic system will supply the majority of braking effort. It is desirable to initiate the mechanical system slightly before the fluid brake system. If only light braking pressure is engaged upon the brake system of the operator, the brake system control valve will reduce the amount of flow to the brake apply piston. To provide for a more rapid filling, and therefore more consistent brake reaction times within the system, a valve mechanism responsive to the reaction torque within the locating brake members is provided to establish a direct fluid connection between the brake apply piston and the line pressure or main pressure of the transmission control.
