Air Force One is designed to provide proportionate braking effort in the towed vehicle by
applying proportioned air based on the pressure in the coach’s braking system to the Air
Force One braking system.
In the event of a breakaway, the reserve-air supply (located within the operating unit) is used to apply the towed vehicle’s brakes. The towed vehicle’s brakes remain applied until the break-away pin is replaced. To be sure that the breakaway tank is charged, you should apply the coach’s brake pedal completely for 3 seconds after the coach has been allowed to completely ‘air-up.”
