Details on C-TEK Standard Disc Brake Rotors

The C-TEK Standard Disc Brake Rotors line by Centric is designed to meet OE specifications for fit, form, and function. This product line focuses on providing reliable braking components that maintain consistent performance under normal driving conditions. The 121.22005 rotor features a vented design with straight vanes to optimize heat dissipation, reducing the risk of brake fade during extended use. The smooth surface finish ensures even pad contact and wear, contributing to longer rotor and pad life.

Technical Specifications and Features

This disc brake rotor has an overall height of 3.602 inches (91.5 mm) and a mounting bolt hole circle diameter of 4.724 inches (120 mm) with five lug holes sized at 0.561 inches (14.25 mm). The floating disc mounting style allows for slight movement to reduce stress and improve rotor longevity. The rotor does not include bearings or an ABS tone ring, so these components must be sourced separately if required for your Land Rover Discovery.

Common Applications and Problem Solving

• Replacement for worn or warped rotors causing brake pulsation
• Addressing reduced braking efficiency due to rotor thickness below discard limits
• Resolving noise issues related to uneven rotor surfaces
• Improving heat management in braking systems with vented rotor design
• Ensuring proper fitment for Land Rover Discovery brake assemblies

Installation Notes and Tips

• Verify rotor dimensions and bolt pattern compatibility with your Land Rover Discovery before installation
• Ensure the rotor thickness is above the discard thickness of 0.866 inches (22.0 mm) for safe use
• Clean rotor surface to remove any protective coatings before mounting
• Torque lug nuts to manufacturer specifications to avoid rotor warping
• Check for proper alignment of the floating disc mounting to prevent uneven wear
