<p>A fluid pressure braking system for an articulated vehicle. The system includes valving which senses a failure in the brake service line connection between the tractor and trailer portions of the vehicle. If a failure in the service line connection is detected, the valving closes communication between the tractor and trailer portions of the vehicle and causes actuation of the trailer emergency brakes. When the brakes of the vehicle are released, the valving automatically resets itself to release the trailer emergency brakes.</p> |
