How the tank fits in the system
Supply air from the tractor fills the trailer tank. When the driver applies the brakes, the relay valve sends air from the tank directly to the brake chambers, so the trailer brakes apply quickly and evenly with the tractor's.
Maintenance tips
- Drain the tank regularly to remove the water and oil that collect from compressed air.
- Inspect mounting straps and brackets for corrosion and looseness.
- Replace any tank that shows dents, deep rust, or leaks at the seams or ports.
