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