Ensuring Proper Air Supply in Trailer Air Tank

How is air supplied to the air tank on a trailer?

Air is supplied to the trailer air tank by pushing in the trailer air supply knob/valve, which controls the air flow from the truck's air compressor to the trailer's brake system.

Supplying air to the trailer air tank is a crucial step in ensuring the proper functioning of the trailer's brake system. The process involves using the trailer air supply knob/valve located in the cab of the truck. By pushing in this knob/valve, air is allowed to flow from the truck's air compressor through the air lines to the trailer's brake system.

It is essential to routinely check the air pressure gauge to confirm that the air pressure is at the appropriate level. Any leaks in the system should be promptly addressed to prevent any potential brake malfunctions while on the road.

In addition to pushing in the trailer air supply knob/valve, connecting the emergency line glad hand is also a critical step. This connection establishes the necessary link between the truck and the trailer for the air supply system to work effectively.

Overall, maintaining a steady air supply to the trailer air tank through proper use of the trailer air supply knob/valve and ensuring a secure connection with the emergency line glad hand are essential practices for safe and efficient operation of the trailer's brake system.
