What are the signs of brake pad wear?

Answer: A — Squeaking or grinding noises, decreased braking performance

The signs of brake pad wear typically include squeaking or grinding noises as well as decreased braking performance. These sounds occur due to the wear indicators built into brake pads, which alert the driver that the pads are nearing the end of their service life. When the brake pads wear down excessively, they can also lead to a reduction in braking effectiveness, making it more difficult to stop the vehicle safely. This combination of auditory cues and performance changes is a clear indicator that the brake pads require immediate attention to prevent further damage to the braking system or even a potential safety hazard on the road. While increased fuel consumption can occur for various reasons, it is not a direct sign of brake pad wear. Visible rust on the brake discs may indicate moisture or corrosion but does not directly relate to the condition of the brake pads themselves. Steering wheel vibrations can be a symptom of several issues, including wheel alignment problems or tire balance, rather than a direct indicator of brake pad wear. Hence, the identification of squeaking or grinding noises along with decreased braking performance remains the primary concern for assessing the condition of brake pads.
