About the C-TEK Standard Disc Brake Rotors Line

The C-TEK Standard Disc Brake Rotors line by Centric is engineered to provide reliable, OEM-quality replacement rotors that meet or exceed factory specifications. This product line focuses on standard vented rotors with features such as cast-in ABS tone rings and smooth surfaces to ensure compatibility with ABS systems and consistent braking performance. The 121.83015 rotor is part of this line, offering a vented design and precise fitment for vehicles requiring these specifications.

Technical Details and Specifications

This disc brake rotor features a vented design with straight vanes to promote efficient heat dissipation during braking, reducing the risk of brake fade. The rotor’s smooth surface ensures even pad wear and optimal contact. The integrated ABS tone ring is cast into the hat, providing reliable signals to the vehicle’s ABS system. With six mounting bolt holes and a bolt circle diameter of 6.752 inches, this rotor fits vehicles designed for this configuration. The overall height and center hole diameter are engineered for precise hub mounting behind the hub, ensuring proper alignment and performance.

Common Applications and Problem Solving

• Replacement for worn or warped rotors causing brake pulsation or noise
• Upgrading to rotors with ABS tone rings for vehicles with ABS systems
• Addressing rotor thickness below discard limits to maintain safe braking
• Resolving uneven pad wear due to rotor surface imperfections
• Improving heat dissipation in vehicles experiencing brake fade under heavy use

Installation Notes and Tips

Ensure the rotor is mounted behind the hub as specified. Verify the mounting bolt hole pattern and center hole diameter match the vehicle’s hub assembly. Clean the rotor surface before installation to remove any protective coatings or contaminants. Check the rotor thickness to confirm it meets or exceeds the nominal thickness of 1.437 inches and is above the discard thickness of 1.320 inches. Proper torque specifications should be followed for mounting bolts to avoid rotor warping.
