Product Line Details: C-TEK Standard Disc Brake Rotors

The C-TEK Standard Disc Brake Rotors line by Centric focuses on delivering reliable, OEM-quality replacement rotors. This product line emphasizes precise fitment and consistent performance, making it suitable for routine maintenance and brake system repairs. The 121.38022 rotor maintains the original equipment specifications for the Saab 9-3, ensuring proper fit and function without modifications.

Technical Specifications and Features

This vented rotor features a smooth surface type that supports even pad wear and braking response. The vented design with straight vanes enhances heat dissipation during braking, reducing the risk of rotor warping under normal operating conditions. The floating disc mounting system allows slight movement to accommodate thermal expansion, improving rotor longevity. The rotor’s overall height measures 45.3 mm (1.783 inches), and it includes three miscellaneous holes for mounting alignment. The five lug holes are spaced on a 110 mm (4.331 inches) bolt circle diameter, matching the Saab 9-3’s wheel hub specifications.

Common Applications and Problem Solving

• Replacement for worn or warped rotors on Saab 9-3 models
• Addresses brake pulsation caused by uneven rotor surfaces
• Improves braking consistency after rotor thinning or damage
• Restores proper rotor thickness to meet safety standards
• Helps reduce brake noise associated with damaged rotors

Installation Notes and Tips

Ensure the rotor thickness is measured before installation to confirm it meets the nominal thickness of 29.8 mm and is above the discard thickness of 27.5 mm. Clean the rotor surface to remove any protective coatings or debris before mounting. Verify the rotor’s center hole diameter and bolt pattern match the Saab 9-3 hub assembly. Since bearings and ABS tone rings are not included, reuse existing components if applicable. Proper torque specifications should be followed when tightening lug nuts to avoid rotor distortion.

Quality Assurance and Warranty

Centric’s C-TEK Standard Disc Brake Rotors are manufactured to meet or exceed OEM standards for fit, form, and function. The 121.38022 rotor undergoes rigorous quality control to ensure durability and consistent braking performance. Warranty coverage details should be confirmed with the product documentation or supplier, as they may vary by region.
