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

The DFC Brake Rotor - Drilled and Slotted - Silver line by Dynamite Friction features rotors engineered for enhanced heat dissipation and improved brake pad bite. The drilled and slotted design helps reduce brake fade by allowing gases and debris to escape, while the zinc silver coating on the hat provides corrosion resistance. This rotor line is tailored for solid rotors with directional surfaces, suitable for vehicles requiring precise braking response.

Technical Description and Specifications

This disc brake rotor is constructed as a solid rotor with a 330 mm outside diameter and an overall height of 62.9 mm. The rotor surface is both drilled and slotted, which aids in maintaining cooler operating temperatures and improving pad contact. The rotor features a plain disc finish and a zinc silver rust-resistant coating on the hat to extend service life. It includes five bolt holes with a 112 mm bolt circle diameter and a center hole diameter of 67 mm, designed to fit specific Mercedes-Benz models. The nominal thickness is 14 mm, with a discard thickness of 11.4 mm, ensuring clear service limits for safe operation.

Compatible Vehicles and Applications

• Compatible with Mercedes-Benz ML320, ML350, ML450, ML500
• Also fits Mercedes-Benz R320, R350, R500 models
• Ideal for replacing worn or damaged front or rear rotors on these vehicles
• Addresses issues such as brake fade, rotor warping, and uneven pad wear
• Suitable for drivers seeking rotors with enhanced heat dissipation and corrosion resistance

Installation Notes and Tips

Ensure the rotor thickness is measured before installation to confirm it exceeds the discard thickness of 11.4 mm. Clean the rotor surface to remove any protective coatings or residues before mounting. Verify bolt hole alignment with the 5-lug, 112 mm bolt circle pattern on your Mercedes-Benz model. Proper torque specifications should be followed to avoid rotor distortion. Directional rotors must be installed with the correct rotation direction for optimal performance.

Quality Assurance and Warranty

Dynamite Friction manufactures the 631-63129L rotor to meet or exceed OEM standards for fit and function. The rust-resistant zinc silver coating helps protect against corrosion, extending rotor life. While specific warranty details are not provided, Dynamite Friction products typically undergo rigorous quality control to ensure reliability and durability in demanding driving conditions.
