• OE rotor replacement needs on rear brake service

Installation Notes

Install on the rear axle only and verify rotor dimensions, bolt pattern, and hub fitment before service. Clean the hub mounting surface thoroughly before installation to help prevent rotor runout. Follow the vehicle manufacturer’s brake bedding procedure after installation to promote even pad transfer and stable braking performance. Confirm fitment by model year and rear position for Hyundai Kona, Hyundai Sonata, Kia K5, or Kia Niro EV before ordering.
