Which indication suggests brake pads need replacing?

A grinding noise when braking is a clear indication that brake pads need replacing. This noise typically occurs when the brake pads have worn down significantly and the metal backing plate of the pad comes into contact with the brake rotor. This metal-on-metal contact can lead to increased damage to the rotor and compromised braking efficiency.

When you hear a grinding noise, it's important to address the issue promptly as it not only affects the performance of the braking system but can also lead to more costly repairs if the rotors are damaged.

While a decrease in braking responsiveness and an increase in pedal travel may also indicate problems with the braking system, they do not specifically signal worn brake pads. Brake fluid leakage points to issues within the hydraulic system, which is unrelated to the condition of the pads themselves. Recognizing the grinding noise as a distinct sign of deteriorating brake pads is crucial for timely maintenance and safety on the road.
