Noisy brakes are more than just a common automotive annoyance; they can be a critical warning sign of underlying mechanical issues. While some sounds may be harmless, others demand immediate attention to prevent potential damage to your vehicle. Here’s an in-depth look at the different sounds brakes can make, what they potentially mean, and why you should never ignore them.
This is one of the most serious noises your brakes can make, akin to driving over a rumble strip on the highway. Typically, a grinding noise indicates that the brake pads have completely worn away and the metal of the pads is scraping directly against the metal of the rotors. This metal-to-metal contact can damage your rotors beyond repair if not addressed immediately. If you hear this sound, it's advisable to stop driving and have your vehicle inspected by a professional.
Often found in vehicles with drum brakes at the rear, a thumping sound can be particularly aggravating. It occurs when the brake shoes engage a groove in the brake drum, similar to a needle following a track on a record player. If the groove is uneven or interrupted, the shoes can snap back against the backing plate, creating a thumping noise. This may indicate that the drums need resurfacing or that the shoes need adjustment.
Common and less severe, squeaking noises are often caused by low-quality or worn-down brake pads. These pads may contain high metal flake content that grinds against the rotor when braking, producing a high-pitched squeal. To avoid this, opt for higher-quality brake pads recommended by your mechanic, which can reduce noise and prolong the life of your brakes.
If you hear a scraping sound while driving or turning, it might be caused by a foreign object such as a rock caught between the rotor and the backing plate. This is common even if you haven’t been off-roading; small debris from normal roads can become lodged in the brakes. Typically, removing the debris resolves the noise, but it's good practice to have your brakes checked to ensure there's no further damage.
Ignoring noisy brakes can lead to more severe problems, including reduced braking efficiency and increased repair costs. Here are some steps to take if your brakes start making unusual sounds:
