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 dependable braking performance with quality materials and precise manufacturing. The 121.99015 rotor fits within this line, offering a vented design and floating mounting to maintain optimal braking efficiency and rotor longevity.

Technical Details and Compatibility

This disc brake rotor features a vented design that helps dissipate heat generated during braking, reducing the risk of brake fade. The floating disc mounting allows for slight movement to accommodate thermal expansion and improve rotor alignment. With a center hole diameter of 2.992 inches (76.000 mm) and 5 lug holes, this rotor is compatible with vehicles requiring these specifications. Note that this rotor does not include an ABS tone ring or bearings.

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 to reduce brake fade during extended use
• Resolving uneven pad wear due to rotor surface irregularities
• Upgrading to a vented rotor for enhanced cooling performance

Installation Notes and Tips

Ensure the rotor thickness is measured before installation to confirm it meets or exceeds the nominal thickness of 0.866 inches (22.000 mm). Clean the rotor surface to remove any protective coatings or debris. Verify the mounting bolt hole circle diameter of 4.724 inches (120.000 mm) and stud/lug hole diameter of 0.654 inches (16.600 mm) match the vehicle specifications. Since bearings and ABS tone rings are not included, reuse existing components or replace separately as needed.
