Which of the following could be a symptom of over-torqued lug nuts?

A symptom of over-torqued lug nuts is brake pedal pulsation during braking. When lug nuts are excessively tightened, they can distort the wheel and lead to misalignment or warping of the brake components. This distortion can prevent the brake rotors from maintaining even contact with the brake pads, causing irregular pressure during braking. As a result, the driver may experience a pulsating sensation in the brake pedal as the braking force is applied inconsistently.

The other options, while they may indicate different issues within the braking or tire systems, are not directly associated with over-torqued lug nuts. Brake fluid leaks typically suggest a problem in the brake hydraulic system, such as worn seals or damaged lines. Uneven tire wear can stem from misalignment or improper inflation but isn't a direct result of lug nut torque. Brake fade refers to a temporary reduction in braking effectiveness, often due to overheating, which is unrelated to the torque of the lug nuts.
