air force one braking
Yahoo Message Number: 111616
We like our Airforce. There are basically three kinds of systems.
One has a box that sits on the floor in front of the driver's seat of the car and attaches to the brake pedal. When an electrical signal from the coach (activated when the coach brake lights go on), a piston pushes the brake pedal down. This is the “brake buddy†system.
The second is a system where the air pressure from the coach air system is connected to a very small pressure reservoir mounted in the car. The air pressure changes on the coach system when the coach brakes are activated are translated into a piston that is mounted onto the brake pedal of the car that has a small cable attached the firewall of the car. When the coach brakes activate, the piston on the brake pedal of the car PULLS the brake pedal towards the firewall, activating the car brakes. This is the Airforce System.
The third is a system that taps in the car Master Brake Cylinder. I can't recall the the manufacturer of these systems. This system translates the coach system into the fluid system that a car uses.
I like the airforce system because when the car is not hitched to the coach, it is invisible. There is nothing to hook / unhook or remove. Hitching is very easy with only an airline to hook up between the coach and the car. It is also very proportional. I have installed two air force systems on each of our two tow cars that we use. The installation was easy. I had a truck repair place install the coach side air outlet. It was very inexpensive.
The airforce system is not cheap, but I believe it is very reliable and will last a long time. Probably longer than the car. It is easy to move from car to car if you replace the car.
Hope this helps. e-trailers.com has a number of interesting tutorials on the different brake systems as well.
