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

The DFC Brake Rotor - Drilled and Slotted - Silver line by Dynamite Friction focuses on rotors that combine drilled holes and slots on the braking surface. This design improves water and gas evacuation during braking, reducing brake fade and maintaining consistent friction. The silver zinc coating on the rotor hat provides corrosion resistance, extending rotor life in various driving conditions. This rotor line is tailored for vehicles requiring vented rotors with directional braking surfaces, such as the Buick Enclave and Cadillac XT5 and XT6.

Technical Specifications and Features

This disc brake rotor is vented to allow better airflow and heat dissipation, which helps prevent overheating during heavy braking. The rotor’s nominal thickness is 30 mm, with a discard thickness of 27 mm, ensuring a clear service limit for safety. The rotor measures 345 mm in outside diameter and 51.3 mm in overall height, matching factory specifications for the listed vehicles. The directional slotted and drilled surface improves braking efficiency by channeling away debris and gases. The rotor hat is finished with a zinc silver coating to resist rust, while the disc surface has a plain finish. It features six bolt holes with a diameter of 16.3 mm and a bolt circle diameter of 120 mm, compatible with the stud/lug pattern of the specified Buick and Cadillac models.

Applications and Problem Solving

• Restores braking performance on Buick Enclave, Cadillac XT5, and XT6 vehicles
• Reduces brake fade caused by heat buildup during extended braking
• Improves water and debris evacuation for consistent stopping power in wet conditions
• Prevents rust and corrosion on rotor hats for longer service life
• Maintains proper rotor thickness and structural integrity for safe braking

Installation Notes and Tips

Ensure the rotor thickness is above the discard thickness of 27 mm before installation. Clean the rotor surface to remove any protective coatings or contaminants prior to mounting. Verify the bolt hole pattern and diameter match the vehicle’s hub assembly. Use proper torque specifications for the six lug bolts to avoid warping. Directional rotors must be installed with the correct rotation direction as indicated by the rotor design to ensure optimal performance.

Quality Assurance and Warranty

Dynamite Friction manufactures the 631-46047L 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 reliable braking performance on Buick Enclave, Cadillac XT5, and XT6 vehicles.
