Brembo Brake Disc

Brake discs are almost always attached to the brake hub. During braking, the brake pads press against the disc brake, reducing the rotational speed of the disc and thus the entire vehicle. Brake discs are usually made of cast iron or steel alloys. Like the brake pads, the brake disc also wears out, but at a slower rate than the pads. With frequent braking, the brake discs heat up significantly and must meet high standards. To withstand extreme loads, there are also discs made of carbon and ceramic.

To achieve increased heat resistance, brake discs are sometimes heat-treated. This involves heating them significantly after production and then cooling them down again. Additionally, there are ventilated brake discs. Perforated or slotted brake discs provide better braking performance in wet conditions, as their indentations help to drain the water sitting on the brake disc more quickly and effectively. Another advantage is that dirt, such as brake dust, disappears from the brake disc more rapidly.
