Arizona Air Brakes CDL Practice Test

What can be a result of improper brake adjustment?

Improved stopping power Brake drag and excessive wear More responsive brakes Increased fuel efficiency

Correct Answer:

Brake drag and excessive wear

Explanation:

Improper brake adjustment can lead to brake drag and excessive wear. When brakes are not adjusted correctly, they can remain partially engaged even when the driver is not applying the brake pedal. This constant friction causes the brake components to heat up more quickly, leading to premature wear and reduced lifespan of the braking system. Additionally, brake drag can significantly reduce the overall efficiency of the vehicle, increase stopping distances, and potentially lead to more serious braking system failures over time. Therefore, maintaining proper brake adjustment is crucial for the safety, performance, and longevity of a vehicle’s braking system.
