Details on C-TEK Standard Disc Brake Rotors

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 consistent braking performance with a smooth surface finish and vented rotor design to help dissipate heat effectively. The pillar vane style enhances airflow, reducing the risk of brake fade during extended use. The floating disc mounting system allows for slight rotor movement, which can improve pad contact and reduce noise. This rotor is engineered specifically for Cadillac SRX models, ensuring proper fitment and reliable operation.

Technical Specifications and Features

The Centric 121.62083 rotor features a 12.559-inch outside diameter and a nominal thickness of 1.020 inches, with a discard thickness of 0.945 inches, indicating when replacement is necessary. The overall height measures 1.894 inches, and the rotor includes six lug holes with a 4.5-inch bolt circle diameter. The center hole diameter is 2.783 inches, designed to fit the hub precisely. This vented rotor uses pillar-style vanes to optimize cooling and reduce thermal stress. It does not include an ABS tone ring or bearings, so these components must be sourced separately if required.

Common Applications and Problem Solving

• Replacement for worn or warped rotors on Cadillac SRX
• Addresses brake pulsation and vibration issues
• Improves heat dissipation to reduce brake fade
• Restores proper rotor thickness for safe braking
• Eliminates noise caused by uneven rotor surfaces

Installation Notes and Tips

When installing the Centric C-TEK Standard Disc Brake Rotor 121.62083, ensure the rotor surface is clean and free of any protective coatings before mounting. Verify the rotor thickness is above the discard limit of 0.945 inches to maintain safety standards. Use proper torque specifications on the 6 lug nuts to avoid rotor warping. Since this rotor does not include bearings or an ABS tone ring, confirm these components are compatible and installed correctly if your vehicle requires them. It is recommended to replace brake pads simultaneously to ensure optimal braking performance.
