A well-maintained automotive brake system can help keep you safe on the road. It is important to recognize the early warning signs of a failing brake system, like a rattling or grinding noise when braking, as it can keep you, your family, and your friends out of possible danger.
Brake noises can mean different things. Sometimes, they are normal and harmless; other times, they are your car’s cry for help. Either way, these noises can come in the form of a rattle, a squeak, or a grinding noise.
Six Reasons Why Your Brakes Make a Grinding Noise
1. Faulty brake pads – Your brake pads wear out faster when you use your car often. Eventually, the backing plates will lose their material, which ultimately results in metal-to-metal abrasions (the rotor against the caliper or the backing plates against the caliper).
Also, if you’re using low-quality brake pads, which are sometimes irregular in shape, there’s a chance they may have excess metal chunks in them. These impurities can damage your rotors (and in some cases, the brake pad itself), resulting in your car making grinding noises.
2. Stuck objects between your rotors and calipers – Do you hear a grinding noise even if you’re not pushing the brake pedal? If you do, look for small solid objects such as stones between your rotors and calipers. These particles should be removed immediately to avoid damaging your vehicle.
3. Worn-out wheel bearing – Alternating grinding noises (quiet to loud and vice versa) along with vibrating motions could be signs of a failing wheel bearing. To fix this problem, replace your bearing right away.
4. Uneven rotor discs – Rotor discs with rough surfaces can cause vibrations, not to mention, produce annoying squeaking sounds, as well. To avoid the issue, get new rotor discs.
5. Damaged shims – Shims are important to your brake pads. They prevent the pads and the rotors from clanging against each other. If you keep driving with damaged shims, not only will you hear grating noises, but your brakes could have limited response, too.
6. Rusty rotors – Do you usually leave your car in your garage for too long? Word to the wise: not driving your car regularly is a bad idea as idleness can bring about rust on your rotors. If the rust spreads onto other parts of your brakes, you can expect to hear bad rotor noise.
A scraping sound when braking could mean a lot in terms of your safety. Be sure to inspect every part of your brake system before driving. Avoid expensive repair costs by replacing the parts that need immediate attention.
