Technical Specifications and Features

This vented disc brake rotor features a straight vane design that promotes efficient airflow to dissipate heat during braking. The rotor’s nominal thickness is 0.862 inches (21.9 mm), with a discard thickness of 0.787 inches (20 mm), ensuring safe replacement intervals. The rotor measures 11.898 inches (302.2 mm) in outside diameter and has an overall height of 2.008 inches (51 mm). The floating disc mounting system allows for slight movement to reduce stress and improve rotor longevity. The smooth surface finish supports consistent pad contact and braking performance. The rotor includes five stud/lug holes with a diameter of 0.622 inches (15.8 mm) and a mounting bolt hole circle diameter of 4.252 inches (108 mm).

Compatible Vehicles and Common Applications

• Replacement rotor for Volvo XC60 models requiring part number 320.39047H
• Addresses issues such as brake rotor warping and uneven pad wear
• Helps resolve corrosion-related rotor degradation
• Improves heat dissipation to reduce brake fade during extended use
• Restores smooth braking performance and reduces noise

Installation Notes and Tips

Ensure the rotor thickness is measured before installation to confirm it is above the discard thickness of 0.787 inches (20 mm). Clean the hub surface thoroughly to prevent uneven rotor mounting. Use proper torque specifications for the five lug nuts to avoid rotor distortion. This rotor does not include bearings or ABS tone rings, so verify compatibility with your vehicle’s existing components. Proper bedding-in of brake pads after installation is recommended to optimize braking performance.
