• Restoring smooth braking surface contact after corrosion or scoring.
• Servicing rear brake systems on select Nissan vehicles.

Installation Notes and Tips

Verify rear fitment by year, make, and model before installation. The rotor is designed for a no-machining installation path, but the brake pads, calipers, and hub condition should be inspected during service. For best system matching, Wagner recommends pairing ES rotors with Wagner brake pads and calipers.
