About the DFC Brake Rotor - Drilled and Slotted - Silver Line

The DFC Brake Rotor - Drilled and Slotted - Silver line by Dynamite Friction is engineered to provide enhanced braking efficiency through its vented design and directional slotted and drilled surface. This rotor line focuses on heat dissipation and debris removal, which helps maintain consistent brake performance and reduces the risk of brake fade during demanding driving scenarios.

Detailed Product Description

This disc brake rotor features a vented design that promotes airflow to reduce heat buildup during braking. The directional slotted and drilled surface improves water and gas evacuation, enhancing braking response and reducing pad glazing. The rotor’s zinc silver hat finish offers corrosion resistance, extending the rotor’s service life. With a nominal thickness of 22 mm and a discard thickness of 19.4 mm, this rotor maintains structural integrity and safety standards. The 5-bolt hole pattern with a 112 mm bolt circle diameter ensures proper fitment on compatible Mercedes-Benz models.

Applications and Problem Solving

• Compatible with Mercedes-Benz GL350, GL450, GL550, GLE400, GLS350d, GLS450, and GLS550 models
• Addresses brake fade caused by excessive heat during heavy braking
• Reduces brake pad glazing and improves pad bite with slotted and drilled surface
• Prevents rust and corrosion with zinc silver hat finish
• Maintains braking performance in wet conditions by evacuating water efficiently

Installation Notes and Tips

• Ensure rotor thickness is above discard thickness (19.4 mm) before installation
• Clean rotor surface before mounting to remove any protective coatings
• Verify bolt hole alignment with vehicle hub (5 holes, 112 mm bolt circle diameter)
• Use proper torque specifications for lug nuts to avoid rotor warping

Quality Assurance

Dynamite Friction manufactures this rotor to meet OEM specifications for fit and function. The rust-resistant coating and vented design contribute to durability and consistent braking performance. Please consult vehicle service manuals for specific warranty details related to brake components.
