Detailed Product Features and Specifications

This DFC Brake Rotor - Drilled and Slotted - Silver is constructed with a plain disc finish and a zinc silver hat finish that provides enhanced protection against rust and corrosion. The rotor features a vented design to improve heat dissipation during braking, reducing the risk of brake fade under demanding conditions. The drilled and slotted surface pattern helps evacuate gases, dust, and water, maintaining consistent contact between the brake pad and rotor surface. With a 5-bolt hole configuration and a bolt circle diameter of 112 mm, this rotor is specifically designed to fit Mercedes-Benz models including the GL350, GL450, GLE400, GLS350d, and GLS450. The directional surface type ensures optimal braking performance when installed correctly according to rotation direction.

DFC Brake Rotor - Drilled and Slotted - Silver Product Line

The DFC Brake Rotor - Drilled and Slotted - Silver line by Dynamite Friction focuses on delivering rotors with enhanced cooling and debris removal capabilities. This product line combines drilled holes and slots on the rotor surface to improve braking efficiency and rotor longevity. The silver zinc coating on the hat area adds a layer of rust resistance, making these rotors suitable for vehicles exposed to varying weather conditions. This part number 631-63146R is a representative example of this line, tailored for specific Mercedes-Benz SUVs and crossovers.

Common Applications and Problem Solving

• Replacement for worn or warped rotors on Mercedes-Benz GL350, GL450, GLE400, GLS350d, and GLS450
• Improves heat dissipation to reduce brake fade during heavy braking
• Helps eliminate brake noise and vibration caused by uneven rotor surfaces
• Maintains consistent braking performance in wet or dusty conditions
• Prevents rust buildup that can lead to rotor surface degradation

Installation Notes and Tips

Ensure the rotor is installed with the directional surface oriented according to the vehicle’s rotation direction for optimal performance. Verify bolt hole alignment with the 5-lug pattern and 112 mm bolt circle diameter. It is recommended to inspect brake pads and hardware during rotor replacement to maintain overall braking system integrity. Proper torque specifications should be followed when securing the rotor to avoid warping or uneven wear.
