About the C-TEK Standard Disc Brake Rotors Line
The C-TEK Standard Disc Brake Rotors line by Centric is designed to meet or exceed OEM specifications for standard replacement rotors. This product line focuses on delivering reliable braking performance with quality materials and manufacturing processes. The 121.68000 rotor features a vented design to help reduce heat buildup during braking, which is critical for maintaining rotor integrity and brake system efficiency in vehicles such as the GMC K1500 and Jeep Grand Wagoneer.
Technical Details and Compatibility
This disc brake rotor is compatible with a range of Chevrolet, GMC, and Jeep models including the Blazer, Cherokee, Grand Wagoneer, J10, Jimmy, K5 Blazer, K10, K10 Suburban, K1500, K1500 Suburban, V10, V10 Suburban, V1500, V1500 Suburban, and Wagoneer. The rotor mounts behind the hub and does not include an ABS tone ring or bearings. Its six mounting bolt holes and precise center hole diameter ensure a secure fit and proper alignment.
Common Applications and Problem Solving
- Replacement for worn or warped rotors causing brake pulsation
- Addressing rotor thickness below discard limits to maintain braking safety
- Improving heat dissipation in vehicles experiencing brake fade
- Restoring smooth braking surface for consistent pad contact
- Upgrading vented rotors for better performance in heavy-duty or off-road use
Installation Notes and Tips
Ensure the rotor thickness is measured before installation to confirm it is above the discard thickness of 1.215 inches (30.86 mm). Clean the rotor surface and hub mounting area to remove rust or debris for proper seating. Use the correct torque specifications for the six mounting bolts to avoid rotor warping. Since this rotor does not include bearings or an ABS tone ring, verify compatibility with your vehicle’s brake system components before installation.
