This is awesome. I didn't know that truck brake lines worked this way.
When you hit the brakes in your truck, it cuts off or lowers the air from the service line? Is there still an anti-lock breaking system for trucks?
The service line works the same as hydraulic brakes, so added pressure causes the breaks to apply. The emergency line supplies air to the trailers air tanks. Without that air, your brakes won't release, and you won't have air suspension.
You can see something that looks like a rubber bladder under there, that's my air suspension..
