Why do brake rotors have holes and slots?

The drilled holes in brake rotors help to vent hot gases away from the braking surface, which can improve cooling. The slots help to remove dust and moisture, ensuring a cleaner and more consistent contact between the pad and the rotor.

Do I need to replace both rear rotors at the same time?

Yes, it is highly recommended to replace brake rotors in pairs. Replacing both the left and right rear rotors at the same time ensures balanced braking performance and prevents uneven wear.

What is the black finish on this rotor?

The black finish on this R1 Concepts rotor is a protective coating applied to prevent rust and corrosion during shipping and storage. It is designed to wear off during the initial break-in period of the brake pads.

About this part

Product Details

When it's time to replace the rear brake rotors on your 2004-2010 Toyota Sienna, especially if you do a lot of stop-and-go driving or carry heavy loads, you'll want a rotor that can handle the heat. This rear left rotor from R1 Concepts features a drilled and slotted design to help manage braking temperatures.

The drilled holes allow gases to escape from the rotor surface, while the slots help sweep away dust and moisture. This combination helps maintain consistent braking performance, especially during repeated stops. The rotor itself is finished in black, giving it a clean look behind your wheels.

This is a direct replacement rotor, meaning it's designed to fit your Sienna's original brake system without modification. Make sure to replace rotors in pairs for balanced braking performance.
