About the C-TEK Standard Disc Brake Rotors Line

The C-TEK Standard Disc Brake Rotors line by Centric is designed to meet OEM specifications for fit, form, and function. This product line focuses on providing reliable, vented rotors that maintain consistent braking performance and heat management. The 121.22010 rotor is part of this line, offering a smooth surface and floating disc mounting to ensure proper alignment and reduced brake judder on compatible Land Rover models.

Technical Details and Specifications

This disc brake rotor features a vented design with straight vanes that facilitate efficient airflow to dissipate heat during braking. The nominal thickness of 0.787 inches (20.000 mm) ensures structural integrity, while the discard thickness of 0.669 inches (17.000 mm) indicates the minimum safe thickness before replacement is necessary. The rotor’s overall height of 2.346 inches (59.600 mm) and outside diameter of 13.780 inches (350.000 mm) are engineered to match the braking system requirements of Land Rover LR3, LR4, and Range Rover Sport vehicles. The floating disc mounting and 5 lug holes with a diameter of 0.591 inches (15.000 mm) provide secure installation and compatibility with OEM hardware.

Common Applications and Problem Solving

• Replacement for worn or warped rotors causing brake vibration or noise
• Restoring braking performance on Land Rover LR3, LR4, and Range Rover Sport
• Addressing rotor thickness below manufacturer discard limits
• Improving heat dissipation to reduce brake fade during heavy use
• Ensuring proper rotor fitment with floating mounting to minimize brake judder

Installation Notes and Tips

When installing the Centric C-TEK Standard Disc Brake Rotor 121.22010, ensure the rotor surface is clean and free of any contaminants. Verify the rotor thickness before installation to confirm it meets or exceeds the nominal thickness specification. Use the correct torque specifications for the 5 lug bolts and confirm the mounting bolt hole circle diameter matches the vehicle hub. Since this rotor does not include bearings or an ABS tone ring, reuse existing components or replace separately as needed. Proper bedding-in of the new rotors and brake pads is recommended to optimize braking performance.
