Which symptoms might indicate that brake pads need to be replaced?

The presence of a grinding noise when applying the brakes is a clear symptom that indicates brake pads may need to be replaced. This noise often occurs when brake pads have worn down excessively, causing the metal backing to come into contact with the brake rotor. This can lead to increased wear on both the rotor and the braking system, resulting in diminished braking performance and potential safety hazards.

While increased fuel efficiency and enhanced vehicle speed are not related to the condition of brake pads, longer stopping distances may also suggest brake wear but are less specific than the unmistakable grinding noise. The grinding sound serves as a direct indicator that the brake pads are no longer effective and may require immediate attention to ensure safe vehicle operation.
