Which of the following is a sign of brake issues that can be detected during an exterior inspection?

During an exterior inspection of a vehicle, identifying signs of brake issues is crucial for maintaining safe driving conditions. The presence of worn brake pads, leaks in the brake system, and unusual sounds when the brakes are applied are key indicators of potential problems.

Worn pads suggest that the braking components are not functioning optimally and may need replacement to ensure effective stopping power. Leaks can signify issues in the brake lines or cylinders, which can compromise the hydraulic pressure necessary for the brakes to work. Unusual sounds, such as grinding or squeaking, can indicate that the pads are excessively worn or that there is an issue with the brake hardware that could affect overall braking performance.

In contrast, excessive fuel consumption relates more to engine efficiency or fuel system issues rather than braking. Battery corrosion is a sign of electrical system issues, which is not relevant to brake inspection. Low tire pressure can affect handling and braking distance, but it does not directly point to problems within the brake system itself. Therefore, the signs recorded in the second choice are direct indicators of brake performance and safety.
