About the C-TEK Standard Disc Brake Rotors Line

The C-TEK Standard Disc Brake Rotors line by Centric offers a range of rotors designed to meet OEM specifications for standard braking applications. This product line focuses on providing solid rotors with smooth surfaces that ensure consistent brake pad contact and reliable performance. The 121.04000 rotor fits within this line as a solid, non-vented rotor option suitable for vehicles requiring precise fitment and standard braking characteristics.

Technical Details and Specifications

This Centric rotor features a solid disc design with a smooth surface type, optimized for vehicles that do not require vented rotors. The nominal thickness of 10.900 mm ensures adequate material for heat dissipation and wear resistance, while the discard thickness of 9.000 mm indicates the minimum safe thickness before replacement is necessary. The rotor’s overall height of 45.700 mm and outside diameter of 227 mm align with specific vehicle fitments requiring these dimensions. The 4 lug holes with a 13 mm diameter and a mounting bolt hole circle diameter of 98 mm provide secure installation compatibility. Note that this rotor does not include an ABS tone ring or bearings.

Common Applications and Problem Solving

• Replacement for worn or warped disc brake rotors
• Restores braking performance on vehicles with solid rotor requirements
• Addresses brake pulsation caused by uneven rotor surfaces
• Suitable for vehicles needing rotors with specific 227 mm diameter and 4-lug configurations
• Prevents brake fade by maintaining proper rotor thickness and surface integrity

Installation Notes and Tips

• Verify rotor dimensions and bolt pattern against vehicle specifications before installation
• Ensure rotor thickness is above discard thickness to maintain safety and performance
• Clean rotor surface and hub mounting area to prevent uneven wear or noise
• Torque lug nuts to manufacturer specifications to avoid rotor warping
• Check for compatibility with brake pads and calipers specific to the vehicle make and model
