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 standard replacement rotors. This product line focuses on delivering reliable braking performance with precise fitment and consistent quality. The 121.66057 rotor maintains the original equipment dimensions and features a vented design to help reduce brake fade under normal driving conditions.

Product Details and Specifications

This disc brake rotor features a vented design with straight vanes to optimize airflow and cooling during braking. The smooth surface finish ensures proper pad bedding and consistent contact. With a center hole diameter of 3.091 inches (78.500 mm) and a mounting bolt hole circle diameter of 5.531 inches (140.500 mm), it fits securely on compatible hubs. The rotor weighs approximately 25.5 lbs (11.59 kgs), balancing durability and performance. Note that this rotor does not include an ABS tone ring or bearings.

Compatible Vehicles and Applications

  • Chevrolet Avalanche, Silverado 1500, Silverado 1500 Classic, Silverado 1500 LD, Suburban 1500, Tahoe
  • GMC Sierra, Sierra 1500, Sierra 1500 Classic, Sierra 1500 Limited, Yukon, Yukon XL, Yukon XL 1500, Savana 1500, Express 1500
  • Cadillac Escalade, Escalade ESV, Escalade EXT, XTS, Cheyenne

Common Issues Addressed by This Rotor

  • Brake rotor warping causing vibration during braking
  • Excessive brake noise due to worn or uneven rotors
  • Reduced braking efficiency from rotor thickness below discard limits
  • Overheating and brake fade during extended use
  • Uneven pad wear caused by rotor surface imperfections

Installation Notes and Tips

Ensure the rotor mounting surface and hub are clean and free of rust before installation. Verify the rotor thickness is above the discard thickness of 1.102 inches (28.000 mm) before mounting. Use proper torque specifications for the 6 lug nuts (0.633 inches diameter) to secure the rotor. Since this rotor does not include bearings or an ABS tone ring, reuse existing components or replace separately as needed. It is recommended to replace brake pads simultaneously for optimal performance.

Quality Assurance and Warranty

Each rotor undergoes strict quality control to ensure durability and consistent braking performance. Warranty coverage details should be confirmed with the product documentation or manufacturer.
