Which type of rotors feature a hollow channel inside of the rotor?

• A. Solid rotors
• B. Ventilated rotors
• C. Slotted rotors
• D. Drilled rotors

Answer: (B)

Ventilated rotors feature a hollow channel inside of the rotor, which is specifically designed to enhance cooling and improve performance during braking. This design allows air to flow through the channels, helping to dissipate heat generated when the brakes are applied. Overheating can lead to brake fade, which diminishes performance, so ventilated rotors help maintain consistent braking power by keeping temperatures in check. The other rotor types do not utilize this channel design. Solid rotors lack any internal channel, leading to less effective heat dissipation. Slotted rotors have grooves cut into the surface that help remove debris and gases, but they do not have the internal channels like ventilated rotors. Drilled rotors feature holes drilled through them for similar purposes as slots, but again, they do not incorporate the hollow channel design that facilitates air flow for cooling.
