• Volvo S80
• Volvo V60 and V60 Cross Country
• Volvo V70
• Volvo XC70

This rotor is designed specifically for these Volvo models, ensuring proper fitment and performance when replacing worn or damaged rotors.

Common Issues Addressed by This Rotor

• Brake rotor corrosion and rust buildup
• Uneven rotor wear causing brake pulsation
• Overheating and brake fade during extended use
• Warped or damaged rotors affecting braking smoothness
• Reduced braking efficiency due to worn rotor thickness

Installation Notes and Tips

Ensure the rotor thickness is above the discard thickness of 9.0 mm before installation. The floating disc mounting requires proper alignment to avoid premature wear. This rotor does not include bearings or ABS tone rings, so verify compatibility with your vehicle’s existing components. Use appropriate torque specifications for the 5 lug bolts with 15.8 mm diameter holes. Clean the rotor surface before installation to remove any protective coatings or contaminants.

Quality Assurance and Warranty

Centric rotors are manufactured to meet or exceed OEM specifications for fit, form, and function. The full coating and high carbon content materials contribute to extended rotor life and consistent braking performance. Warranty information should be confirmed with the supplier or manufacturer, as it may vary by region.
