What is the result of inadequate brake adjustment?

Inadequate brake adjustment leads to longer stopping distances and an increased risk of brake failure, which can significantly compromise safety. When brakes are not properly adjusted, they may not apply sufficient force to effectively slow down or stop the vehicle. This can result from components being out of alignment, leading to uneven wear or a lack of responsiveness when the brake pedal is engaged.

Longer stopping distances mean that it will take more time and distance for the vehicle to come to a complete stop, which becomes critical in emergency situations where quick deceleration is necessary to avoid collisions. Increased risk of brake failure occurs because poorly adjusted brakes can lead to overheating, premature wearing of brake components, and potential complete brake failure if they are unable to engage properly.

In contrast, the other choices would imply results contrary to safe vehicle operation. More effective braking, better fuel economy, and improved tire alignment are all outcomes associated with well-maintained and properly adjusted brake systems, not those that are inadequately adjusted.
