Which of the following is a common indication of brake problems?

Strange noises when braking are a common indication of brake problems because they often signal that brake components, such as the brake pads, rotors, or drums, are worn or malfunctioning. For example, squeaking or grinding noises can suggest that the brake pads are thin and may need replacement. Additionally, unusual sounds can indicate that there is debris stuck in the braking system or that the brake fluid level is low. Recognizing these sounds early can help prevent more severe issues, such as complete brake failure, thus ensuring safer driving conditions.

In contrast, increased fuel efficiency typically has no direct correlation with brake performance and does not indicate any issues. Steering wheel vibrations may point to problems with wheel alignment or suspension rather than the brakes specifically. Decreased tire pressure is primarily related to tire health and performance, and while it affects overall vehicle handling, it is not a direct indicator of brake-related problems.
