Abstract
An electronically controlled brake system includes a brake actuator wherein a valve is electrically controlled to maintain the spring chamber in the non-actuated position during normal operation. However, should there be a failure in the electrical system, then the spring chamber is allowed to set the brake actuator. The “failure” could also include a diagnostic system included in the control which identifies a failure in control operation. In this way, should there be an electrical failure, either in the control or power circuits, the truck is stopped.
