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

The DFC Brake Rotor - Drilled and Slotted - Silver line by Dynamite Friction focuses on rotors that combine drilled holes and slots to improve brake pad bite and reduce heat buildup. The silver zinc coating on the rotor hat provides corrosion resistance, extending rotor life in demanding driving conditions. This product line is tailored for drivers seeking rotors that maintain consistent braking performance on Mercedes-Benz SUVs and crossovers.

Technical Specifications and Features

This disc brake rotor features a vented design with a 330 mm outside diameter and a 67 mm center hole diameter, ensuring proper fitment and cooling efficiency. The rotor’s 5-bolt hole pattern with a 112 mm bolt circle diameter matches the wheel hub specifications of Mercedes-Benz GL and ML series models. The directional slotted and drilled surface helps channel away brake dust and gases, improving pad contact and reducing brake fade during extended use.

Compatible Mercedes-Benz Models

• GL320, GL350, GL450, GL550
• ML320, ML350, ML450, ML500, ML550
• R320, R350, R500

Common Applications and Problem Solving

• Reduces brake fade caused by excessive heat buildup
• Improves braking response and pad bite under wet conditions
• Minimizes rotor warping through enhanced heat dissipation
• Prevents rust and corrosion on rotor hats for longer service life
• Maintains consistent braking performance on Mercedes-Benz SUVs

Installation Notes and Tips

Ensure the rotor surface is clean and free of oil or debris before installation. Verify the bolt hole pattern and center hole diameter match your vehicle’s hub. It is recommended to replace brake pads when installing new rotors to optimize braking performance. Torque lug nuts to manufacturer specifications and perform a test drive to confirm proper brake operation.

Quality Assurance and Warranty

Dynamite Friction rotors are manufactured to meet or exceed OEM standards for fit and function. The rust-resistant zinc silver coating on the rotor hat helps protect against corrosion. While specific warranty details for part number 631-63131L should be confirmed with the distributor, Dynamite Friction products typically come with a limited warranty against manufacturing defects.
