About the C-TEK Standard Disc Brake Rotors Line

The C-TEK Standard Disc Brake Rotors line by Centric focuses on delivering dependable, OEM-quality replacement rotors. This product line emphasizes precise fitment and consistent braking performance, making it suitable for vehicles that require standard vented rotors with floating mounting. The 121.69004 rotor is part of this line, ensuring compatibility with specific vehicle models that demand these exact specifications.

Technical Details and Specifications

This Centric rotor features a vented design that helps reduce brake fade by allowing air to circulate between the rotor surfaces. The floating disc mounting system accommodates slight movement, which can improve rotor alignment and reduce uneven wear. With a smooth surface type, the rotor ensures even brake pad contact for consistent braking response. The rotor’s dimensions, including a 12.571-inch outside diameter and 6 lug holes with a 0.563-inch diameter, are critical for matching specific vehicle hubs and wheel configurations.

Common Applications and Problem Solving

• Replacement for worn or warped rotors causing brake pulsation
• Addressing rotor thickness below discard limits to maintain safe braking
• Improving heat dissipation in vehicles experiencing brake fade
• Resolving uneven pad wear due to rotor surface irregularities
• Upgrading to a vented rotor for enhanced braking under load

Installation Notes and Tips

Ensure the rotor mounting surface and hub are clean and free of debris before installation. Verify the rotor’s center hole diameter and bolt pattern match the vehicle specifications. Since bearings and ABS tone rings are not included, reuse existing components or source separately if required. Proper torque specifications should be followed for mounting bolts to avoid rotor warping.

Quality Assurance and Warranty

Centric C-TEK Standard Disc Brake Rotors are manufactured to meet or exceed OEM standards for fit, form, and function. While specific warranty details for part number 121.69004 should be confirmed with the supplier, Centric generally offers coverage against defects in materials and workmanship to ensure long-term reliability.
