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. Just like the brake pads, the brake disc also wears out, although it does so more slowly than the pads. During frequent braking events, the brake discs heat up significantly and must therefore meet the highest 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 again after production and then cooling them down. Additionally, there are ventilated brake discs. Perforated or slotted brake discs provide better braking performance in wet conditions, as their indentations allow water sitting on the brake disc to be drained away more quickly and effectively. Another advantage is that dirt, such as brake dust, disappears from the brake disc more rapidly.
