The brake disc, also known as the rotor, is a critical component of a vehicle's disc brake system. It is the part that rotates with the wheel and is pressed against by the brake pads to create friction and slow down or stop the vehicle. The material used is typically gray iron, a type of cast iron known for its durability and heat resistance.
Disc designs can vary, with some being solid and others featuring internal vanes or fins to improve cooling. These ventilated discs are commonly used on the front wheels of heavier vehicles because they help dissipate heat more effectively, preventing overheating and ensuring consistent braking performance.
