Installation Notes and Tips

Inspect calipers, slides, and parking brake components before installation. Clean the hub mounting surface and verify rotor seating to help prevent runout-related noise or pulsation. For Sonata applications, confirm whether the vehicle uses a manual parking brake setup before ordering. Follow proper pad bedding procedures after installation to promote even transfer material and consistent stopping performance.
