Detailed Product Features and Specifications

This disc brake rotor features a vented design that enhances heat dissipation, reducing the risk of brake fade during extended use. The nominal thickness of 32 mm ensures durability, while the discard thickness of 30 mm indicates the minimum safe thickness before replacement is necessary. With an outside diameter of 335 mm and an inside diameter of 67 mm, this rotor is specifically sized for precise fitment on compatible Mercedes-Benz vehicles. The rotor includes five bolt holes with a diameter of 15.2 mm, accommodating secure mounting. The height of 64.5 mm supports proper alignment within the braking system.

About the DFC Hi-Carbon Alloy GEOMET Coated Rotor - Drilled Line

The DFC Hi-Carbon Alloy GEOMET Coated Rotor - Drilled product line by Dynamite Friction incorporates high-carbon alloy material combined with a GEOMET coating. This coating provides corrosion resistance and extends rotor life. The drilled design aids in heat and gas dissipation, contributing to consistent braking performance. This rotor line is tailored for drivers seeking reliable stopping power and rotor longevity in their Mercedes-Benz CL550, S400, and S550 models.

Applications and Problem Solving

• Replacement for worn or warped rotors on Mercedes-Benz CL550, S400, and S550
• Improves heat management to reduce brake fade during heavy braking
• Addresses rotor corrosion issues with GEOMET coating
• Restores braking efficiency and pedal feel
• Compatible with OEM specifications for bolt pattern and dimensions

Installation Notes and Tips

Ensure the rotor thickness is measured before installation to confirm it exceeds the discard thickness of 30 mm. Properly torque the five 15.2 mm bolt holes to manufacturer specifications to avoid rotor warping. The vented design requires clearance within the brake caliper assembly, so verify fitment on Mercedes-Benz CL550, S400, and S550 models. It is recommended to replace brake pads simultaneously for optimal braking performance.

Quality Assurance and Warranty

Dynamite Friction rotors are manufactured to meet or exceed OEM standards for fit, form, and function. The GEOMET coating enhances corrosion resistance, contributing to longer service life. While specific warranty details are not provided, this rotor is designed for durability and consistent performance in Mercedes-Benz braking systems.
