About the C-TEK Standard Disc Brake Rotors Line

The C-TEK Standard Disc Brake Rotors line by Centric focuses on providing dependable, OE-quality replacement rotors. This product line emphasizes precise fitment and consistent performance, making it suitable for routine maintenance and brake system repairs on vehicles such as the Ford C-Max and Volvo C30.

Detailed Product Description

This Centric disc brake rotor features a vented design with pillar-style vanes that enhance airflow to reduce heat buildup during braking. The smooth surface finish supports even pad wear and quiet operation. With a floating disc mounting system, the rotor allows slight movement to accommodate thermal expansion and reduce stress on the braking components. The rotor’s dimensions, including a 10.937-inch outside diameter and 5 lug holes spaced on a 4.252-inch bolt circle diameter, are engineered to match specific Ford and Volvo models precisely. The absence of an ABS tone ring means this rotor is intended for vehicles without ABS sensor integration on the rotor itself.
