• Uses coach air to create vacuum for towed vehicle's power brakes and proportionately apply brakes
• Total Coach Protection separates and protects the air supply on the coach

This kit includes everything needed for the motorhome side of the Air Force One system. Note that a separate towed vehicle kit is required for complete installation. Also known as SMI part number SM99627.
