What does it indicate if your vehicle's air tanks are not drained regularly?

When air tanks are not drained regularly, it can lead to potential moisture and oil buildup. Compressed air used in braking systems can carry moisture and oil, which, if not drained, can accumulate in the air tanks. This buildup can cause corrosion and damage to the braking components, adversely affecting their performance and reliability.

Regularly draining air tanks is vital for maintaining the integrity of the braking system, ensuring that moisture does not interfere with the air brakes that rely on a clean air supply. Without proper drainage, the consequences can include reduced braking efficiency and increased wear on air lines and valves. Therefore, it's crucial to routinely check and drain air tanks to prevent these issues and maintain safety on the road.
