Product Description
The Demco 6238 is a replacement installation kit for the Demco Air Force One supplemental braking system. Air Force One is an air-operated system for motorhomes with air brakes: it uses a pilot signal from the coach's air brake system to apply the towed vehicle's brakes in direct proportion to the coach's braking. Its operating unit mounts under the hood of the towed vehicle, and a compact actuator mounts on the brake pedal arm with the cable anchor secured to the firewall.
This kit includes fittings and mounting hardware. It does not include the coach air connection assembly, breakaway cable or check valve.

Pro tipSupplemental braking: what to know
- Often required by law. Most U.S. states and Canadian provinces require brakes on a towed vehicle above a certain weight, and towing equipment makers generally expect one.
- Match your motorhome. Some systems are designed for coaches with air brakes and others for hydraulic brakes — check which your RV has.
- Portable vs. permanently installed. Portable units move between cars; installed systems are quicker to hook up day to day.
