ABSTRACT:
A braking system controlled by an operator's pedal for a vehicle equipped with a mechanically actuated brake clutch pack in which a cam is rotated in response to movement of a brake pedal to operate a pressure-modulating hydraulic valve to direct fluid pressure to an hydraulic actuator extendable under pressure to engage a force transfer member secured to an actuator rod, which rod is connected to apply the clutch pack when tensioned.
