If you’ve ever heard your brakes grinding, you know it’s not a pleasant sound. Brake grinding can be caused by a variety of issues, but the most common cause is worn brake pads. When brake pads wear down, they no longer make full contact with the brake rotors. This causes a grinding sound as the metal backing plate rubs against the rotor. In some cases, the brake pads may wear down to the point where they start to damage the rotors. If left unchecked, this can eventually lead to more serious problems like brake failure.

If you hear your brakes grinding, it’s important to have them checked out by a professional as soon as possible. Let’s look closer at your Audi’s brake system and parts that can cause noises as they wear down and need replacement.

How Your Brakes Work

In any brake system, there are four main parts that will eventually wear down and need to be replaced. The first is the brake pad.

  • Brake pads are what make contact with the brake rotor, causing friction and slowing the wheel. Over time, brake pads will wear down and need to be replaced.
  • The second part is the brake rotor. The brake rotor is a metal disc that the brake pads grip in order to stop the wheel. Like brake pads, brake rotors will also wear down over time and will need to be replaced.
  • The third part is the brake caliper. The brake caliper houses the brake pads and helps to apply pressure to the rotor. If the caliper wears down, it can cause the pads to not make full contact with the rotor, making it less effective at slowing down the wheel.
  • The fourth and final part is the brake fluid. Brake fluid helps to transfer pressure from the pedal to the calipers, causing them to squeeze the pads against the rotor. Over time, brake fluid can become contaminated and will need to be replaced in order to maintain braking performance.

Common Causes of Grinding Noises from Your Brakes

Brake grinding is caused by four main reasons. The first reason is because of brake pad deposits. If your brake pads have any kind of deposits on them, it will cause a grinding noise when you press the brake. You can usually clean the brake pads with a brake cleaner to remove any deposits.

Secondly, brake grinding on your Audi can occur due to poor brake installation. If your brake pads are not installed correctly, they will make a grinding noise when you press the pedal. Make sure to have a professional mechanic install your brake pads to avoid this issue.

Grinding noises while braking can be caused by glazing of the brake rotors. This happens when the brake rotors get too hot and start to melt the brake pads. To prevent this from happening, make sure to keep your brake rotors clean and free of debris.

Finally, grinding noises can occur due to warped brake rotors. If your brake rotors are warped, they will not spin evenly and will make a grinding noise when you press the brake pedal. You can usually fix this problem by having a professional mechanic resurface the brake rotors.

Brake grinding is annoying and can be dangerous if it is not fixed properly. Make sure to take your car to a professional mechanic if you are having any issues with your brakes.
