What can be a sign of worn brake pads?

A squeaking noise when braking is a common sign of worn brake pads. As brake pads wear down over time, their friction material can become thin, causing metal indicators within the pads to come into contact with the brake rotor. This contact produces a high-pitched squeal or squeak, which serves as an audible warning to the driver that the brake pads need to be inspected or replaced. A vehicle's braking system is crucial for safety, and recognizing these signs promptly can prevent further damage to the braking system and ensure safe operation of the vehicle.

The other choices do not directly relate to worn brake pads. Flashing dashboard lights might indicate various issues, such as problems with engine sensors or other systems, but they are not specific to brake pad wear. Increased fuel consumption can result from many factors, such as engine problems or tire pressure, and isn't associated with the condition of brake pads. Unusual engine vibrations may point to issues with the engine or drivetrain rather than the braking system. Identifying the right symptoms is critical for effective vehicle maintenance.
