Which condition can indicate that brake pads may need to be replaced?

Noise during braking is a significant indicator that brake pads may need to be replaced. As brake pads wear down, they can produce various sounds, such as squeaking, grinding, or squealing. These noises usually occur because the material on the pads has worn to the point where a metal indicator touches the rotor, alerting the driver that replacement is necessary. This sound serves as a warning to check the brake system to ensure safety and prevent further damage.

Increased fuel efficiency is not related to the condition of brake pads; rather, it pertains to how effectively the vehicle uses fuel. Steering pull, which can indicate alignment or suspension issues, does not directly relate to the condition of the brake pads. Dashboard lights typically signal various issues in a vehicle, such as low fluid levels or other system malfunctions, but they may not specifically indicate the need for brake pad replacement. Each of these other conditions does not serve as a direct warning regarding the status of brake pads, making noise during braking the most relevant condition here.
