• Helps eliminate noise or squealing related to rotor wear
• Suitable for vehicles requiring vented rotors for heat management

Installation Notes and Tips

Ensure the rotor surface and hub are clean and free of rust or debris before installation. Verify the rotor thickness is above the discard thickness specification of 30.00 mm.
