What is a potential hazard of neglecting brake maintenance?

Neglecting brake maintenance can significantly increase safety risks, making it the most relevant choice. Proper brake function is critical for safe vehicle operation, as brakes are essential for stopping and controlling a vehicle. When brake components are not maintained, issues such as worn brake pads, low fluid levels, or damaged rotors can arise, potentially leading to brake failure. This increases the risk of accidents, impacting both the driver and others on the road.

In contrast, improved ride quality, increased air quality, and decreased maintenance costs do not directly relate to the absence or neglect of brake maintenance. In fact, poor brake performance could lead to a harsher ride due to vibrations or pulling, while safety hazards do not contribute positively to air quality. Additionally, neglecting maintenance often leads to higher costs in the long run due to emergency repairs or accidents, rather than decreased maintenance costs. Therefore, understanding the vital role of brakes in vehicle safety underscores why addressing maintenance is critical.
