Details on C-TEK Standard Disc Brake Rotors

The C-TEK Standard Disc Brake Rotors line by Centric focuses on providing dependable, OE-quality replacement rotors that meet or exceed factory specifications. This product line emphasizes consistent thickness and smooth surface finishes to ensure proper pad contact and braking efficiency. The vented rotor design with curved vanes helps maintain optimal operating temperatures by promoting airflow, reducing the risk of brake fade during extended use. The floating disc mounting system allows for slight rotor movement, which can improve braking response and reduce noise.

Technical Specifications and Features

This Centric rotor features an overall height of 1.878 inches (47.7 mm) and a mounting bolt hole circle diameter of 4.417 inches (112.2 mm). It includes one miscellaneous hole and does not come with ABS tone rings or bearings. The solid yet vented construction balances strength and heat dissipation, making it suitable for the braking demands of Mercedes-Benz E320 and E350 vehicles. The smooth surface type ensures even pad wear and consistent braking performance.

Common Applications and Problem Solving

• Replacement for worn or warped rotors causing brake pulsation
• Addressing reduced braking efficiency due to rotor thickness below discard limits
• Eliminating noise or vibration from uneven rotor surfaces
• Improving heat dissipation to prevent brake fade during heavy use
• Restoring proper rotor dimensions for safe and reliable braking

Installation Notes and Tips

• Verify compatibility with Mercedes-Benz E320 or E350 before installation
• Ensure rotor thickness is within nominal and discard specifications (1.181 inches nominal, 1.079 inches discard)
• Clean mounting surfaces and check hub for debris to ensure proper rotor seating
• Torque lug nuts to manufacturer specifications to avoid rotor warping
• Inspect brake pads and replace if worn to maintain optimal braking performance
