What indicates that brake pads need replacement?

• A. Increased brake pedal resistance
• B. Diminished braking performance or squeaking noises
• C. Flashing warning lights only
• D. Excessive heat from the brake fluid

Answer: (B)

Diminished braking performance or the presence of squeaking noises are key indicators that brake pads need replacement. When brake pads wear down, they lose their ability to create sufficient friction against the brake rotor, resulting in decreased braking effectiveness. This could manifest as a longer stopping distance or a feeling that the brakes are less responsive.

Additionally, many brake pad designs include wear indicators, which produce a squeaking or grinding noise to alert the driver that the pads are nearing the end of their usable life. This noise serves as an audible warning that encourages proactive maintenance to ensure safety. If brakes are allowed to continue to wear without replacement, it can lead to more severe damage to the braking system, which is why addressing these signs promptly is crucial for vehicle safety.
