An unusual noise when braking is a clear indication that the brake pads may need to be replaced. Brake pads often come equipped with wear indicators or are designed in such a way that they emit a high-pitched squeal when they have worn down to a certain level. This noise serves as a warning to the driver that it is time to assess the condition of the brake pads. Ignoring such sounds can lead to further damage to the braking system and compromised safety.

Increased acceleration and steering wheel vibration, while they may indicate issues with the vehicle's performance or the braking system, are not direct indicators of worn brake pads. Increased acceleration could suggest a different issue, possibly with the throttle or engine performance rather than the brakes specifically. Steering wheel vibration often points to problems such as warped brake rotors, tire imbalance, or suspension issues rather than the state of the brake pads themselves.

Thus, the correct answer focuses on the noise produced, which specifically relates to the condition of the brake pads and serves as a practical alert for maintenance.
