Brake squeal is something every car owner just accepts and gets used to. Once your brakes start to squeal, it’s time to replace them. That’s something that has been ingrained in every driver’s mind after their first few years behind the wheel of a car. Porsche wants to debunk the myth behind squeaky brakes, so it made a video about this particular subject.
Porsche has With some pretty serious weaponry in its arsenal, like the 911 GT2 RS, the 911 GT2 RS and the 918 Spyder, and a long history when it comes to motorsport racing. So it knows a thing or two about developing braking systems.
As it explains in the video below, squealing, at least on its vehicles, is normal, and there are a few reasons for this.
For one, developing powerful braking systems with high-end materials, like carbon ceramics, means that Porsche is focusing on braking performance first and foremost, which puts noise reduction further down on the list. The second issue is related to the size of the brakes themselves. Even with high-end materials, using brake pads to stop a quickly-spinning rotor will result in some sort of vibration. Larger, stronger brakes means that there will be more vibrations, which leads to more squeals.
Having a little squeal at low speeds or when pulling into a parking lot isn’t a big deal and is normal. But when you spend upwards of $55,000 on a sports cars, we’re pretty sure it can be annoying. Still, we could live with a little brake squeak if it means the car will decelerate as it should.
