What is the result of an air brake system being out of adjustment?

An air brake system that is out of adjustment leads to increased stopping distance. This occurs because, when brakes are not correctly adjusted, they may not apply the necessary braking force effectively. This reduced force can directly impact a vehicle's ability to decelerate or stop in a timely manner, resulting in longer distances required to halt the vehicle safely. In the context of school buses, where safety is paramount due to transporting children, properly functioning brakes are crucial for ensuring the ability to stop quickly in emergency situations. Therefore, being aware of brake adjustments and conducting regular maintenance checks is essential for maintaining safe driving conditions.
