How does moisture affect air brake components?

Moisture has a significant impact on air brake components, primarily because it can cause corrosion and freezing of air lines. Air brakes operate using compressed air and, if moisture is present in the system, it can lead to the development of rust within the lines and other components. This corrosion can ultimately result in malfunctions and reduced efficiency of the braking system.

Furthermore, when the air temperature drops, moisture can freeze and lead to ice blockages within the air lines. This can inhibit the proper flow of air needed for the brakes to engage and disengage effectively, potentially causing dangerous situations while driving. Therefore, maintaining dry air in the brake system is essential for ensuring optimal performance and safety in vehicles equipped with air brakes. The use of air driers and moisture traps is a common practice to mitigate these issues.
