How often should you drain the air tanks to remove moisture?

Draining the air tanks to remove moisture is vital for the proper functioning of the air brake system. Over time, moisture can accumulate in the air tanks, which can lead to corrosion and potentially cause brake failure or malfunction. By draining the air tanks daily or before each trip, you ensure that any excess moisture is removed, thereby maintaining the integrity and reliability of the air brake system.

Regularly removing moisture helps prevent issues such as frozen brake lines and air system failures, particularly in extreme weather conditions where moisture can freeze and create blockages. This practice is a key part of maintaining safety and ensuring the vehicle operates efficiently.

While other options suggest different frequencies for draining the tanks, they do not align with best practices for air brake maintenance. Daily or trip-based draining reflects an understanding of the potentially variable conditions the vehicle may encounter, ensuring more consistent performance.
