Details on the DFC Brake Rotor - Drilled and Slotted - Silver Line

The DFC Brake Rotor - Drilled and Slotted - Silver line by Dynamite Friction focuses on rotors that combine drilled holes and slots to improve braking performance under demanding conditions. The drilled and slotted surface helps reduce brake fade by allowing heat and gases to escape more efficiently, while the vented rotor design further aids in cooling. The zinc silver coating on the rotor hat provides corrosion resistance, extending the rotor's service life.

Technical Specifications and Features

This disc brake rotor features a nominal thickness of 32 mm and a discard thickness of 29.4 mm, ensuring a clear service limit for safe operation. The rotor's 330 mm outside diameter and 54.6 mm overall height are designed to match the OEM specifications for the listed Mercedes-Benz models. The rotor includes five bolt holes with a 112 mm bolt circle diameter and a 67 mm center hole diameter, ensuring precise fitment. The directional slotted and drilled surface improves braking efficiency by channeling away water and debris, which is especially beneficial in wet or harsh driving conditions.

Applications and Problem Solving

• Replacement for worn or warped rotors on Mercedes-Benz GLE and ML series vehicles
• Improves heat dissipation to reduce brake fade during heavy braking
• Helps maintain consistent braking performance in wet or dirty environments
• Addresses rotor corrosion issues with rust-resistant zinc silver coating
• Restores proper braking feel and pedal response for safer driving

Installation Notes and Tips

Ensure the rotor surface is clean and free of any protective coatings before installation. Verify the rotor thickness is within the nominal range and above the discard thickness limit. Use proper torque specifications for the 5 bolt holes with a 112 mm bolt circle diameter to secure the rotor. It is recommended to inspect brake pads and replace them if worn to maximize braking performance. Directional rotors must be installed following the indicated rotation direction for optimal function.

Quality Assurance and Warranty

Dynamite Friction manufactures this rotor to meet or exceed OEM standards for fit, form, and function. The rust-resistant zinc silver coating on the rotor hat enhances durability against corrosion. While specific warranty details are not provided, Dynamite Friction products typically undergo rigorous quality control to ensure reliability and safety for Mercedes-Benz GLE300d, GLE350, and ML350 brake system applications.
