Why are My Brakes Grinding?

Grinding Brakes
We’ve all heard it—that grinding noise when you hit the brakes. What exactly does that noise mean, however, and what causes it?

There are many reasons as to why your brakes are grinding, but no matter the reason, it’s always important to fix the issue as soon as possible to avoid vehicle damages and accidents.

So, to ensure your safety, here are a few situations where your brakes can make a grinding noise and what you need to do to fix the problem.

Brakes Grinding When Stopping
If you hear your brakes grinding when stopping or slowing down, then your brake pads, or lack thereof, are to blame. Your brakes pads need to be thick enough to ensure optimum performance and stopping power. With time, though, your brake pads can wear down.

When your brake pads are below the recommended thickness, they will start to emit a squealing noise every time you press on the brake pedal. This lets you know that it’s time to replace them. If you ignore this audible warning, the brake pads will wear down completely, and that squealing sound can turn into a grinding noise.

In this situation, the grinding noise is caused by the brake disc and the caliper rubbing together. The sound is usually heard when you stop your car, but you may also feel the brake pedal rumble as you step on it. The best way to fix this issue is to have your brake pads replaced immediately.

Brakes Grinding When Driving
You may also hear your brakes grinding when you’re driving at a constant speed. This can be caused by rocks and debris lodged between the caliper and the rotor. In this situation, you’ll want to have the debris removed from the system right away. Failure to do this can result in severe damage to the brake system and other performance parts.

While you can remove rocks and debris from your brakes yourself, it’s always best to go to a professional, especially if you don’t have any experience working with cars. Just schedule a service appointment with a dependable dealership and tell the service professionals that your brakes are grinding when you’re driving. Then, take your car in, and they’ll remove any debris from your brakes. Once that’s complete, the grinding noise should disappear.

Brakes Grinding When Stopping Suddenly
Another common instance where your brakes may cause a grinding noise can be when you suddenly slam on the brakes. If you slam on the brakes in a panic-stop situation, you’ll hear a grinding noise and feel the brake pedal rumble. However, this shouldn’t be a cause for concern if your brakes pads are sufficiently thick.

If you hear grinding when you stop suddenly, it’s likely due to your Anti-Lock Braking System (ABS). In a panic-stop situation, the ABS will automatically activate to prevent wheel lockups and skidding. The system works by pumping the brakes to ensure stability and control which causes the grinding noise and the rumbling brake pedal.

Once the car has stopped or when you take your foot off the pedal, the grinding should stop. If your brakes continue to grind, you’ll want to schedule a brake repair immediately because this could be a sign of worn brake pads.
