How do you identify a proper brake adjustment?

Identifying proper brake adjustment is crucial for the safety and efficiency of a vehicle equipped with air brakes. The correct answer focuses on brakes not dragging and properly releasing when not applied. When brakes drag, it can lead to excessive wear on brake components, overheating, and reduced fuel efficiency. Proper brake adjustment ensures that when the brakes are not engaged, they fully release, allowing the vehicle to move freely without unnecessary resistance.

Moreover, well-adjusted brakes should operate smoothly and effectively when engaged, providing the driver with responsive stopping power. If the brakes do not release properly, it can cause the vehicle to behave unpredictably and may increase stopping distances, which is dangerous especially in emergency situations. This is why ensuring that brakes do not drag and fully release is a key indicator of proper adjustment.
