About the Centric GCX Elemental Protection Product Line

The Centric GCX Elemental Protection Disc Brake Rotors - Full Coating, High Carbon Content line focuses on rotors that combine advanced coating technology with high carbon steel construction. This combination helps reduce rust and extends rotor life while maintaining consistent braking performance. The full coating on both the disc and hat surfaces protects critical areas from environmental damage, making it suitable for demanding driving conditions often encountered by Land Rover vehicles.

Technical Specifications and Features

This rotor features a nominal thickness of 1.339 inches (34.000 mm) and a discard thickness of 1.235 inches (31.000 mm), ensuring precise wear limits for safety. The outside diameter measures 14.961 inches (380.000 mm), with an overall height of 2.445 inches (62.100 mm). The rotor is vented with pillar-style vanes to optimize airflow and heat dissipation during braking. The center hole diameter is 3.110 inches (79.000 mm), and it supports a 5-stud lug pattern with 0.591 inch (15.000 mm) diameter holes on a 4.724 inch (120.000 mm) bolt circle diameter. The rotor weighs approximately 34.35 lbs (15.6 kgs), balancing strength and weight for effective braking performance.

Applications and Problem Solving

• Replacement rotor for worn or warped disc brakes on Land Rover Defender 130, Discovery, Range Rover, and Range Rover Sport
• Addresses brake noise and vibration issues caused by uneven rotor surfaces
• Helps prevent rust and corrosion-related rotor damage in harsh environments
• Improves heat management to reduce brake fade during extended use
• Supports consistent braking performance for safe vehicle operation

Installation Notes and Tips

Ensure the rotor thickness is above the discard thickness of 1.235 inches (31.000 mm) before installation. The floating disc mounting design requires proper alignment to avoid noise and uneven 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 mounting bolts on the 120 mm bolt circle diameter to secure the rotor properly.
