Detailed Features
1. Chemical Specification
2. Physical Properties
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 slow or stop the vehicle. Typically made from gray iron, it provides excellent heat dissipation and durability. The design can vary, with some discs being solid while others feature vanes or fins to enhance cooling. Ventilated discs are commonly used in high-performance or heavy-duty applications, such as on front wheels where more heat is generated.
