What is the potential danger of having water or oil in the air tanks?

The presence of water or oil in the air tanks poses a significant risk because these contaminants can freeze in colder temperatures. When this happens, the moisture can form ice, potentially blocking the air lines that travel to the brake system. If the air supply to the brake components is compromised due to freezing, it can lead to brake failure, which is extremely dangerous for vehicle operation. Proper maintenance of air systems, including regular checks for moisture accumulation, is crucial to ensure safe braking performance, especially in cold weather conditions. In this context, recognizing the importance of keeping air systems clean and free of liquid contaminants is critical for the reliability of the braking system.
