No inertia adjustable system can match this braking profile, period. The towed vehicle experiences the same perfect braking symmetry as each individual brake on the coach.

As such, the exhaust brake and transmission retarder have no effect on the AFO. The brake actuator is compact, mounting on the brake arm of the towed vehicle and securing to the firewall with just one self-drilling screw. Once installed, the entire system is invisible and always ready for towing with no takedown. Total Coach Protection, an exclusive AFO attribute, is a process that separates and protects the air supply on the coach.

Only Demco includes the components necessary to meet these important safety regulations. If the towed vehicle separates or the towing system fails, the coach air is protected. AFO is the safest air brake system available. No other air-operated system offers this level of safety and control.

The Coach Air Assembly is pre-assembled and pre-tested for function and leaks. All fittings are included and are push-to-connect style DOT rated. The proprietary design makes binding and cable hang-ups impossible as all the force is completely linear—no pulleys, just one self-drilling screw to secure the cable anchor to the firewall. Other pulley systems have six plus screws and require large, flat surfaces directly behind the brake arm to work reliably—a commodity not afforded by many late model vehicles.

No need to ask if AFO is compatible with your towed vehicle. Air Force One fits all makes and models—from smallest Smart and Fiat to the largest diesel pickup and Hummer H2 and everything in between including hybrids—AFO fits them all.

Any time the brakes are applied in the towed vehicle, the light is on. AFO is a revolutionary product that will apply truly proportionate brake effort in your towed vehicle.

Air-over-hydraulic brake systems operate using a combination of compressed air and hydraulic pressure, and the release of the air and hydraulic pressure engages the master cylinder. It then applies pressure to the valves, and the brake fluid is released.

The brakes then exert friction on the tires, which stops them. Air-over-hydraulic brake systems contain an air-over-hydraulic power cylinder. This cylinder has both an air cylinder and a hydraulic cylinder inside, which work in tandem with each other. The air and hydraulic cylinders each contain a piston and common rod. The air cylinder's piston is a larger diameter than the hydraulic cylinder's piston. It had disc brakes and the two master cylinders were air operated and the air diaphragms would push the hydraulic master cylinder.
