• Addresses brake noise caused by uneven rotor surfaces
• Helps reduce brake fade from excessive heat during frequent stopping
• Prevents rust buildup that can lead to rotor pitting and premature wear
• Restores proper brake pedal feel and stopping performance

Installation Notes and Tips

Ensure the rotor thickness is measured before installation to confirm it is above the discard thickness of 24.00 mm. Clean the rotor surface to remove any protective coating residue before mounting. Verify that the mounting bolt hole circle diameter of 114.30 mm and the 5 lug holes align correctly with the vehicle hub. It is recommended to replace brake pads simultaneously to ensure optimal braking performance and rotor longevity.
