Product Line Details: C-TEK Standard Disc Brake Rotors

The C-TEK Standard Disc Brake Rotors line by Centric offers a balance of quality and value for standard braking applications. These rotors are designed to meet or exceed OEM specifications, providing consistent performance and fitment for vehicles like the Mercedes-Benz S350 and SL500. The vented design with curved vanes enhances heat dissipation, reducing the risk of brake fade during normal driving conditions.

Technical Specifications and Features

This disc brake rotor features a vented design with curved vanes that promote efficient airflow to maintain optimal operating temperatures. The smooth surface finish ensures even pad contact and braking response. With a nominal thickness of 0.866 inches (22.000 mm) and a discard thickness of 0.764 inches (19.400 mm), this rotor maintains structural integrity throughout its service life. The overall height of 2.291 inches (58.200 mm) and outside diameter of 11.811 inches (300.000 mm) are engineered to match the original equipment dimensions for the Mercedes-Benz S350 and SL500. The rotor mounts using five lug holes spaced on a 4.409 inch (112.000 mm) bolt circle diameter, with a center hole diameter of 2.638 inches (67.000 mm).

Applications and Problem Solving

• Replacement for worn or warped rotors on Mercedes-Benz S350 and SL500
• Addresses brake pulsation caused by uneven rotor surfaces
• Improves heat dissipation to reduce brake fade during extended use
• Restores proper rotor thickness for safe braking performance
• Compatible with vehicles lacking ABS tone ring requirements

Installation Notes and Tips

Ensure the rotor thickness is measured before installation to confirm it meets or exceeds the discard thickness of 0.764 inches (19.400 mm). Clean the rotor surface to remove any protective coatings or debris before mounting. Verify the mounting bolt hole circle diameter of 4.409 inches (112.000 mm) and stud/lug hole diameter of 0.602 inches (15.300 mm) match the vehicle specifications. This rotor does not include bearings or an ABS tone ring, so those components must be reused or replaced separately as needed.
