About the C-TEK Standard Disc Brake Rotors Line

The C-TEK Standard Disc Brake Rotors line by Centric offers rotors designed to meet OEM specifications for fit, form, and function. This product line focuses on providing solid rotors with smooth surfaces that are suitable for standard braking systems without ABS tone rings. The 121.99075 rotor is part of this line, ensuring compatibility with vehicles requiring a solid rotor design and precise dimensional tolerances.

Detailed Product Description

This Centric disc brake rotor features a solid construction with a smooth surface type, optimized for vehicles that do not require vented rotors or ABS tone rings. The rotor’s outside diameter of 279.9 mm and nominal thickness of 12 mm provide a robust braking surface, while the discard thickness of 10 mm indicates the minimum thickness before replacement is necessary. The rotor mounts via a 5-lug pattern with 14 mm diameter holes arranged on a 118 mm bolt circle, and the center hole diameter of 70.8 mm ensures proper hub fitment. Weighing 9.27 kg, this rotor balances durability and manageable weight for effective braking performance.

Common Applications and Issues Addressed

• Replacement for worn or warped rotors causing brake pulsation
• Restoring braking efficiency on vehicles with reduced rotor thickness
• Addressing noise or vibration issues related to rotor surface wear
• Upgrading to OEM-spec rotors for consistent braking feel
• Ensuring proper fitment for vehicles requiring a 5-lug, 279.9 mm diameter rotor

Installation Notes and Tips

• Verify vehicle compatibility by matching rotor dimensions and bolt pattern
• Ensure rotor thickness is above discard thickness before installation
• Clean rotor surface and hub mounting area to prevent uneven wear
• Torque lug nuts to manufacturer specifications to avoid rotor warping
• Check for ABS tone ring requirements; this rotor does not include one
