What is the recommended moisture level for brake air tanks?

The recommended moisture level for brake air tanks is that it should be drained regularly to prevent freezing and corrosion. This is crucial because moisture in the air brake system can lead to several problems, including the formation of ice in cold temperatures, which can impede the proper functioning of the brakes. Furthermore, the presence of moisture can cause corrosion within the air tanks and components, potentially leading to system failures and unsafe conditions.

By routinely draining the air tanks, operators can eliminate the build-up of moisture and maintain the integrity and performance of the brake system. This preventive maintenance is essential for ensuring safety and reliability while operating the vehicle. Regular checks help to ensure that the air system remains as dry as possible, thereby reducing the risk of issues related to moisture.
