What is one effect of driving with improperly adjusted brakes?

Driving with improperly adjusted brakes can lead to increased stopping distance and potential brake failure. When brakes are not adjusted correctly, they do not engage or release as they should. This can result in the vehicle requiring a longer distance to come to a complete stop, which is particularly dangerous in emergency situations or when driving at higher speeds. If the brakes are significantly misaligned or inadequately functioning, it can ultimately lead to brake failure, risking the safety of the driver, passengers, and other road users.

In contrast, the other choices do not accurately reflect the consequences of having improperly adjusted brakes: decreased fuel efficiency may occur for other mechanical reasons, a smoother ride would be a result of properly functioning suspension rather than the brakes, and less wear on tires does not typically relate to brake adjustment but rather to alignment and overall vehicle maintenance. Overall, ensuring that brakes are properly adjusted is critical for maintaining safety and driving performance.
