A grinding sound emanating from the brakes indicates metal-on-metal contact, signifying worn brake pads or other serious mechanical issues. Continuing to operate a vehicle in this condition can lead to further damage, including rotor scoring, caliper damage, and potentially complete brake failure.
Addressing this issue promptly is paramount for safety and can prevent costly repairs. Ignoring the grinding noise can compromise stopping power, increasing the risk of accidents. Historically, brake systems have evolved significantly, but the core principle remains: friction is used to decelerate the vehicle. When the friction material wears down, metal components make contact, creating the characteristic grinding sound, which is a clear signal that immediate attention is required.
