Why Do I Hear Intermittent Grinding Noise Each Time I Hit My Porsche Brakes?

The braking system is one of the most fundamental systems of your Porsche. If your Porsche brakes produce noise that is unusual, you should have it checked and fixed as soon as possible. This is because brake noise is a warning that your braking system is faulty. Many a times, drivers ignore brake noises for a long time. As a result, the problem worsens and they end up paying dearly for their ignorance in terms of expensive repairs and replacement. It is more serious when you find yourself in a situation where you cannot stop your Porsche causing accidents and even fatalities. Therefore, being able to distinguish the different types of brake noises is helpful in understanding the severity of brake problems. Read on to find out more about common brake noises and what they mean.

Brake Rattling

Brake rattling is one of the most prominent concerns for drivers. Most of the time, you will notice rattling when you release the brake pedal. The rattling is like the sound you get when you shake a spray paint can. The most common culprit behind brake rattling is the brake pads. Due to heat expansion, the brake pads may rattle, especially if they do not have anti-rattle shims installed. However, it is important to note that if you experience rattling when your foot is on the brake pedal, the brake pads are not the cause. Also, the rattle caused by brake pads should not be consistent. This is a sign that you may have a more complicated problem with your brakes.

Brake Grinding

Noise that points towards a more serious problem in your Porsche is brake grinding. If you press the brake pedal and you get a loud grinding sound, there is a high chance that it is caused by the rotor disc. This happens when the rotor disc comes into contact with the brake caliper. It is mostly as a result of worn out brake pads or brake rotors. This problem is common among vehicle owners who do not take their cars for brake servicing regularly.

Another possibility is that there may be some objects stuck in the brake caliper. When objects such as stones get stuck in the caliper, your Porsche brakes will make an intermittent grinding sound when driving. You may eliminate the object by driving your Porsche forward and backward repeatedly. However you should first look for some space, away from traffic and crowds. If that does not work you need to service your brakes immediately. This will help you save a lot of money that you would otherwise throw away on expensive repairs and replacements.

If when you hit your Porsche brakes you hear grinding noises from your wheels that alternates from quiet to loud, your wheel bearing may be damaged. In addition to the noise you will notice vibrations. This problem may be resolved by simply replacing the damaged wheel bearings. Whenever you get brake noises, you should have your Porsche checked for faults as soon as possible.
