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

The DFC Brake Rotor - Drilled and Slotted - Silver line from Dynamite Friction focuses on rotors that combine drilled holes and slots to improve brake pad bite and reduce heat buildup. The silver zinc coating on the hat area provides corrosion resistance, extending rotor life. This product line is designed to meet the demands of heavy-duty vehicles requiring consistent braking under load, such as the Cadillac Escalade and GMC Yukon XL.

Technical Specifications and Features

This disc brake rotor features a vented design with a 410 mm outside diameter and a height of 59.1 mm, allowing for efficient heat dissipation during braking. The rotor’s surface is both drilled and slotted, which helps to evacuate gases, dust, and water, improving braking performance in various conditions. The rotor is directional, meaning it is designed to rotate in a specific direction to maximize cooling and debris removal. The zinc silver hat finish and rust-resistant coating protect against corrosion, maintaining rotor integrity over time. It includes six bolt holes with a 16 mm diameter and a bolt circle diameter of 139.7 mm, compatible with vehicles requiring a 6-lug pattern.

Compatible Vehicles and Applications

• Cadillac Escalade and Escalade ESV
• Chevrolet Silverado 1500 and Silverado 1500 LD
• GMC Sierra 1500 and Sierra 1500 Limited
• Chevrolet Tahoe
• GMC Yukon and Yukon XL

This rotor is suitable for drivers seeking to replace or upgrade the front or rear disc brake rotors on these specific GM models, ensuring proper fitment and performance.

Common Issues Addressed by This Rotor

• Brake fade caused by excessive heat buildup
• Uneven brake pad wear due to poor rotor surface design
• Corrosion and rust on rotor surfaces reducing lifespan
• Reduced braking efficiency in wet or dusty conditions
• Vibration or noise from warped or damaged rotors

Installation Notes and Tips

Ensure the rotor is installed in the correct directional orientation to maintain optimal performance. Verify that the bolt hole pattern and center hole diameter (78.6 mm) match the vehicle specifications. It is recommended to inspect brake pads and hardware during installation and replace if necessary. Proper torque specifications should be followed to avoid rotor warping.
