Regularly draining air tanks is crucial for the effective functioning of an air brake system in commercial vehicles. When air tanks are not drained, water that has naturally condensed due to temperature changes remains in the system. This water can accumulate and, in colder weather, it can freeze.

When the condensation freezes, it can block the air lines, which may cause braking problems when the driver needs to apply the brakes. If the system has ice, it can prevent the air brakes from operating correctly, posing a significant safety hazard on the road. This highlights the importance of maintaining the air brake system by periodically draining air tanks to prevent water accumulation and the potential freezing that can occur, thereby ensuring reliability and safety in braking performance.
