If you own a BMW, you may have noticed that your brakes tend to squeal every time you use them. While this can be annoying, it’s not actually a sign of anything wrong with your car. In this post, we’ll explain why bmw squeaky brakes and how to fix it if it’s bugging you. Keep reading to learn more!
How Do BMW Brakes Work?
BMW brakes are designed to provide the excellent stopping power and fade resistance. The system uses two different types of brake pads, one for the front wheels and one for the rear. The front pads are made of a harder material than the rear pads, which helps to evenly distribute braking forces.
The rear pads also have a wear sensor that will trigger a warning light on your dash when they need to be replaced.
Causes Of BMW Squeaking Brakes
Brake noise can be normal, for example when you first press down on the brake pedal in the morning. This is because your wheels spin against metal calipers covered with performance pads that create higher levels of friction than typical cars use and result in high-pitched squeals or squeaks from them while stopping at low speeds.
In contrast to brake noise which is normally nothing to worry about, there are times when it may signify an issue. If you hear a noise that sounds like tearing paper, it means that the brake pads are becoming thinner. As the brake pads begin to wear down, it becomes more challenging to bring your vehicle to a stop safely.
There are a few different reasons why your BMW brakes might start squealing.
Contamination
If your pads get contaminated with dirt, debris, or even water, they can start to make noise when you brake. This is usually more of a problem in wet or muddy conditions, but it can happen any time your pads get dirty.
The Pad Insulation Is Missing
If the pads aren’t installed correctly, they can rub against the rotors or calipers, which will cause noise. This is usually something that happens at the factory, but it’s possible for a mechanic to install the pads incorrectly as well.
The Brake Pads Are Worn
The most common cause is simply that the brake pads are getting worn down and need to be replaced. If you ignore the problem, eventually the pads will wear down so much that they’ll start to damage the rotors. That can lead to some pretty serious problems, so it’s always best to take care of the issue as soon as you notice it.
The Brakes Are Overheated
If you’ve been driving hard and using the brakes a lot, they can start to squeal from the heat. This is usually not a cause for concern, but if it happens often, it could be a sign that your brake system isn’t cooling down properly.
The Rotor Cut Is Wrong
If the rotors are cut incorrectly, they can also cause squealing. This is a pretty rare problem, but it’s something to keep in mind if you’re having brake problems and you’ve recently had your rotors replaced.

Try cleaning the pads with brake cleaner or sanding them down to remove the debris. If that doesn’t work, you’ll need to replace them.
If the problem is that the rotors are cut incorrectly, you’ll need to have them replaced. This is a pretty rare problem, but it’s something to keep in mind if you’re having brake problems and you’ve recently had your rotors replaced.
