Detailed Product Description

This Centric GCX Elemental Protection Disc Brake Rotor, part number 320.39043F, is specifically designed for Volvo vehicles including the S60, S60 Cross Country, S80, V60, V60 Cross Country, V70, and XC70 models. The rotor features a fully coated disc and hat finish that helps prevent rust and corrosion, extending the rotor's service life. Its vented design allows for better heat dissipation during braking, reducing the risk of brake fade under demanding conditions.

The rotor's nominal thickness is 0.429 inches (10.9 mm), with a discard thickness of 0.354 inches (9.0 mm), ensuring it meets safety and performance standards. The smooth surface finish provides consistent contact with brake pads, contributing to stable braking performance. The floating disc mounting design helps accommodate thermal expansion and contraction, improving rotor longevity and brake system reliability.

About the Centric GCX Elemental Protection Disc Brake Rotors - Full Coating Line

The Centric GCX Elemental Protection Disc Brake Rotors - Full Coating product line focuses on providing rotors with comprehensive corrosion protection through a full coating process. This coating covers both the braking surface and the rotor hat, which helps maintain rotor integrity in harsh environments. This line is suitable for drivers seeking rotors that resist rust and maintain performance over time, especially in regions with wet or salty road conditions.

Common Applications and Problem Solving

• Replacement for worn or warped rotors on compatible Volvo models
• Addressing brake noise caused by rust or uneven rotor surfaces
• Improving braking consistency in vehicles exposed to corrosive environments
• Reducing rotor surface corrosion that can lead to premature brake pad wear
• Enhancing heat dissipation to prevent brake fade during extended use

Installation Notes and Tips

Ensure the rotor thickness is within specifications before installation, checking the nominal and discard thickness values. The rotor is designed for a 5-lug bolt pattern with a 4.252 inch (108 mm) mounting bolt hole circle diameter, compatible with specified Volvo models. Use proper torque specifications when mounting to avoid rotor warping. Since this rotor does not include bearings or an ABS tone ring, verify compatibility with your vehicle’s existing components.

Quality Assurance and Warranty

Centric rotors undergo rigorous quality control to meet OEM standards for fit, form, and function. The full coating process provides added protection against corrosion, contributing to the rotor’s durability. Warranty details should be confirmed with the supplier or manufacturer, as they may vary by region and application.
