The brake disc is usually in the form of a disc or disc that is firmly attached to the wheel hub and rotates with it. During braking, the frictional surface of the brake disc is pressed between the brake pads, thereby producing a braking effect.

The xDrive designation used on BMW vehicles is reserved for models equipped with intelligent all-wheel drive. However, different BMW models have different types of xDrive.
