Which component assists in ensuring effective braking by reducing brake fade?

Ventilated rotors play a crucial role in ensuring effective braking by minimizing brake fade, particularly under heavy use. Brake fade occurs when the braking system overheats, leading to a reduction in braking performance. Ventilated rotors are designed with air channels or vents that allow for increased airflow and heat dissipation during operation. This enhanced air circulation helps lower the temperature of the brake components, thereby maintaining the brake system's efficiency and effectiveness even during repeated applications.

By contrast, the other components listed, such as brake boosters and calipers, serve essential functions in the braking system but do not directly address the issue of heat management that is pivotal in preventing brake fade. Brake pads also contribute to friction, but their material and composition are primarily focused on providing stopping power rather than cooling. Therefore, the design of ventilated rotors specifically targets the reduction of heat buildup, making them key in combating brake fade.
