What can dual parking control valves allow you to do?

Dual parking control valves are specifically designed to give the driver the ability to release the spring-loaded emergency or parking brakes temporarily. This feature is particularly useful when a truck is parked in a location that makes moving it difficult. By using the dual parking control valves, the driver can actuate the brakes to allow a short move, making it easier to position the vehicle without needing to manually disengage the brakes.

This functionality is essential for maneuvering in tight spaces or when making adjustments in a loading or unloading area. It is important to note that this system should only be used for short distances and when conditions allow safe movement, as the brakes need to be effectively re-engaged after the maneuver. Other answer choices do not relate to the function of dual parking control valves and address functions unrelated to their purpose.
