Detailed Features
1. Chemical Specification
Â
2. Physical Properties
The brake disc (or rotor) is the rotating component of a wheel’s disc brake system, where the brake pads press against it to slow or stop the vehicle. Typically made from gray iron, it's a crucial part of modern braking systems. The design can vary—some are solid, while others feature internal vanes or fins to improve heat dissipation. Ventilated discs are commonly used on front wheels due to higher heat generation and weight. This design helps reduce thermal stress and ensures better performance over time.
