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

The Centric GCX Elemental Protection Disc Brake Rotors - Full Coating line focuses on providing rotors with a complete protective coating on both the disc surface and hat. This full coating helps prevent rust and corrosion, extending rotor life and maintaining smooth braking performance. The vented design with curved vanes enhances airflow to reduce heat buildup during braking, which is critical for maintaining consistent brake feel and preventing premature wear.

Technical Specifications and Features

This disc brake rotor features a smooth surface finish and a vented, solid rotor type optimized for heat management. The rotor weighs approximately 24 lbs (10.91 kgs), balancing durability and performance. The center hole diameter measures 2.638 inches (67 mm), and the mounting bolt hole circle diameter is 4.409 inches (112 mm), accommodating 5 lug holes with a diameter of 0.602 inches (15.3 mm). The floating disc mounting system allows for slight movement to reduce stress and improve rotor longevity.

Applications and Problem Solving

• Replacement for worn or warped rotors on Mercedes-Benz E350, E500, E550, SL500, and SL550
• Addresses brake noise and vibration caused by uneven rotor surfaces
• Helps prevent rust and corrosion that can degrade braking performance
• Improves heat dissipation to reduce brake fade during extended use
• Restores proper rotor thickness for safe and effective braking

Installation Notes and Tips

• Ensure rotor discard thickness of 1.181 inches (30 mm) is not exceeded before replacement
• Clean hub surface before installation to ensure proper rotor seating
• Torque lug nuts to manufacturer specifications for Mercedes-Benz models
• Check for ABS tone ring compatibility; this rotor does not include an ABS tone ring
• Inspect brake pads and replace if worn to maintain optimal braking performance
