摘要： A braking system for a work vehicle may generally include a hydraulically actuated brake, a tank containing hydraulic fluid and a brake valve fluidly connected between the tank and the hydraulically actuated brake. The brake valve may be movable between an on position and an off position for controlling a flow of the hydraulic fluid from the tank to the hydraulically actuated brake. The brake valve may include a first solenoid coil and a second solenoid coil, with each of the solenoid coils being configured to be independently energized and de-energized for moving the brake valve between the on and off positions. The system may also include a first control device electrically connected to the first solenoid coil for energizing and de-energizing the first solenoid coil and a separate second control device electrically connected to the second solenoid coil for energizing and de-energizing the second solenoid coil.
