What is the purpose of the drilled holes on this rotor?

The drilled holes on the rotor surface help to vent hot gases and heat away from the braking surface. This can lead to more consistent braking performance, especially during repeated stops or hard braking situations.

Is this rotor sold individually or as a pair?

This listing is for a single rear left brake rotor. If you need to replace both rear rotors, you will need to order two of these units.

What is the black finish on the rotor for?

The black finish on the rotor is primarily for corrosion resistance, helping to prevent rust and maintain a clean appearance. It also contributes to the overall look of the braking system.
