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

The DFC Brake Rotor - Drilled and Slotted - Black line by Dynamite Friction focuses on rotors that combine drilled holes and slots to improve brake pad bite and reduce heat buildup. The zinc black hat finish provides corrosion resistance, extending rotor life in demanding conditions. This product line is tailored for drivers seeking enhanced braking performance with reliable durability on compatible Mercedes-Benz SUVs.

Technical Description and Specifications

This disc brake rotor features a vented design that promotes airflow between the rotor faces, helping to dissipate heat generated during braking. The drilled and slotted surface improves water and gas evacuation, reducing brake fade and maintaining consistent stopping power. The rotor’s nominal thickness is 32 mm with a discard thickness of 29.4 mm, ensuring a long service life before replacement is necessary. The zinc black coating on the hat section offers rust resistance, which is critical for maintaining fitment and performance over time. With 5 bolt holes spaced on a 112 mm bolt circle diameter, this rotor is engineered to fit securely on Mercedes-Benz GL350, GL450, GLE400, GLS350d, and GLS450 models.

Applications and Problem Solving

• Reduces brake fade during heavy or repeated braking
• Improves heat dissipation to prevent rotor warping
• Enhances braking performance in wet conditions by evacuating water
• Minimizes brake dust buildup on rotor surface
• Provides corrosion resistance to extend rotor lifespan

Installation Notes and Tips

Ensure the rotor is installed on compatible Mercedes-Benz models listed for part number 633-63146L. Verify bolt hole alignment with the 5-lug, 112 mm bolt circle diameter pattern. Clean the rotor surface before installation to remove any protective coatings or residues. Proper torque specifications should be followed to avoid rotor distortion. It is recommended to replace brake pads simultaneously to maintain optimal braking performance.

Quality Assurance

Dynamite Friction manufactures this rotor to meet or exceed OEM specifications for fit, form, and function. The rust-resistant zinc black hat finish and vented rotor design contribute to durability and consistent braking performance. Warranty information is available through the manufacturer and should be consulted for coverage details.
