Product Line Details: DFC Brake Rotor - Drilled and Slotted - Silver

The DFC Brake Rotor - Drilled and Slotted - Silver line by Dynamite Friction is engineered to provide enhanced braking efficiency through its drilled and slotted design. This configuration helps reduce brake fade by improving heat dissipation and removing debris from the rotor surface. The silver zinc coating on the rotor hat offers corrosion resistance, extending the rotor's service life. This product line is tailored for drivers seeking a balance between performance and durability in their braking components.

Technical Specifications and Features

This disc brake rotor features a solid construction with a 300mm outside diameter and a 58.5mm overall height, ensuring compatibility with specified Mercedes-Benz models. The rotor's nominal thickness is 12mm, with a discard thickness of 10mm, indicating when replacement is necessary to maintain safe braking. The drilled and slotted surface is directional, designed to optimize braking performance by enhancing cooling and reducing gas buildup during braking. The rotor includes five bolt holes with a 112mm bolt circle diameter and a center hole diameter of 67mm, matching factory specifications for a secure fit.

Applications and Problem Solving

• Replacement rotor for worn or warped brake discs on Mercedes-Benz CL550, S400, S550, and SL550
• Improves heat dissipation to reduce brake fade during heavy braking
• Helps prevent rust and corrosion with zinc silver coating on the rotor hat
• Slotted and drilled design assists in removing brake dust and gases for consistent braking
• Directional surface enhances braking response and rotor longevity

Installation Notes and Tips

Ensure the rotor is installed with the directional surface oriented correctly according to the vehicle’s rotation. Verify that the bolt hole pattern and center hole diameter match the hub assembly for proper fitment. Measure rotor thickness before installation to confirm it meets or exceeds the discard thickness of 10mm. It is recommended to replace brake pads when installing new rotors to maintain optimal braking performance.

Quality Assurance

Dynamite Friction rotors are manufactured to meet OEM specifications for fit and function. The rust-resistant coating on the rotor hat helps extend service life in various driving conditions. While no specific warranty information is provided, adherence to quality manufacturing standards ensures reliable performance for Mercedes-Benz CL550, S400, S550, and SL550 vehicles using part number 631-63078R.
