Product Line Details: Centric GCX Elemental Protection Disc Brake Rotors - Full Coating

The Centric GCX Elemental Protection Disc Brake Rotors - Full Coating line is designed to provide extended rotor life through a comprehensive coating process. This full coating protects both the braking surface and the rotor hat from rust and corrosion, which is especially beneficial for vehicles like the Audi Q7, Porsche Cayenne, and Volkswagen Touareg that may encounter varied weather conditions. The vented design improves heat dissipation, helping maintain consistent braking performance under load.

Technical Description and Specifications

This disc brake rotor features a nominal thickness of 28 mm and a discard thickness of 26 mm, ensuring a precise fit and optimal braking surface life. The rotor’s outside diameter measures 330 mm, suitable for the specified vehicle models. The rotor is vented, allowing for better heat management during braking, which reduces the risk of brake fade. The smooth surface finish supports even pad wear and consistent braking feel. The rotor includes five bolt holes with a mounting bolt hole circle diameter of 130 mm, matching the factory specifications for the Audi Q7, Porsche Cayenne, and Volkswagen Touareg. The coated hat finish complements the fully coated disc surface to resist corrosion in critical areas.

Common Applications and Problem Solving

• Replacement for worn or warped rotors on Audi Q7, Porsche Cayenne, and Volkswagen Touareg
• Addresses rotor corrosion and rust issues due to environmental exposure
• Improves braking consistency by reducing heat-related brake fade
• Restores proper rotor thickness for safe braking performance
• Eliminates vibration and noise caused by uneven rotor surfaces

Installation Notes and Tips

• Ensure rotor thickness is above discard thickness (26 mm) before installation
• Clean mounting surfaces to prevent rotor runout and vibration
• Use proper torque specifications for the 5 lug bolts to secure the rotor
• Check compatibility with ABS sensors as this rotor does not include an ABS tone ring
• Inspect brake pads for wear and replace if necessary to ensure optimal rotor performance
