Details on C-TEK Standard Disc Brake Rotors

The C-TEK Standard Disc Brake Rotors line by Centric is designed to provide dependable braking performance that aligns closely with original equipment standards. This product line focuses on delivering rotors with precise dimensions and quality materials to ensure proper fitment and function. The 121.44091 rotor features a vented design with straight vanes to optimize airflow and heat dissipation, reducing the risk of brake fade during extended use. Its smooth surface finish promotes even pad wear and consistent braking response.

Technical Specifications and Features

This disc brake rotor has an overall height of 2.594 inches (65.9 mm) and includes six mounting bolt holes sized at 0.425 inches (10.8 mm) diameter. The rotor mounts behind the hub, consistent with Toyota’s original design. It does not include an ABS tone ring or bearings, so these components must be sourced separately if required. The vented rotor design with straight vanes enhances cooling efficiency, which is critical for maintaining braking performance under load.

Common Applications and Problem Solving

• Replacement for worn or warped rotors on Toyota 4Runner and T100
• Addresses brake pulsation caused by uneven rotor thickness
• Improves heat dissipation to reduce brake fade during towing or heavy use
• Restores proper rotor thickness to maintain safe braking distances
• Eliminates noise and vibration associated with damaged rotors

Installation Notes and Tips

• Verify compatibility with your specific Toyota 4Runner or T100 model year before installation
• Ensure mounting surfaces and hub are clean and free of debris for proper rotor seating
• Torque mounting bolts to manufacturer specifications to avoid rotor warping
• Replace brake pads when installing new rotors to ensure optimal braking performance
• Check for ABS tone ring requirements as this rotor does not include one
