ABSTRACT:
A hydraulically-actuated brake system for off-road, heavy vehicles that includes separate accumulators for braking the front and rear brakes and brake valves that are both manual and pilot actuated for controlling the flow of hydraulic fluid from the accumulators to the brakes. Also included are valves for comparing the pressure in the front and rear accumulators so that, should one of the systems become low, the brakes are immediately set. Also included is a manual valve for overriding the brake valves in the event that a malfunction occurs in one of the brake valves.
