What role do cross-drilled or slotted rotors play in a braking system?

Cross-drilled or slotted rotors are specifically designed to enhance airflow and reduce brake temperature during operation. The perforations or slots allow for better ventilation, facilitating the escape of gases that can build up between the rotor and brake pad during heavy braking. This improved airflow helps maintain lower temperatures within the braking system, which can lead to more consistent brake performance, reduced brake fade, and ultimately increase the overall safety and efficiency of the braking process.

By reducing the temperature of the braking system, these designs can also prolong the lifespan of brake pads and rotors, ensuring that the braking system remains effective over a longer period. While aesthetics might be a consideration for some, the primary functional benefits of cross-drilled and slotted rotors are directly related to performance and efficiency in braking scenarios.
