Detailed Product Description

This disc brake rotor, part number 604-47091, is part of the DFC GEOSPEC Coated Rotor line by Dynamite Friction. The rotor features a vented design that helps dissipate heat more effectively during braking, reducing the risk of brake fade under heavy use. The rotor’s hat is finished with a Geospec silver grey coating that provides rust resistance, extending the rotor’s service life in various driving conditions. The plain disc finish and smooth surface ensure consistent pad contact and braking performance. With six bolt holes sized at 16 mm diameter and a bolt circle diameter of 139.7 mm, this rotor is engineered for precise fitment on compatible vehicles.

DFC GEOSPEC Coated Rotor Product Line

The DFC GEOSPEC Coated Rotor line focuses on corrosion resistance and durability through specialized coatings applied to the rotor hat. This coating helps protect critical areas from rust and corrosion, which is especially beneficial for vehicles exposed to harsh weather or road salt. The 604-47091 rotor exemplifies this approach by combining vented rotor technology with a protective finish, making it suitable for heavy-duty applications on trucks and SUVs.

Compatible Vehicles and Applications

• Cadillac CELESTIQ, Escalade, Escalade ESV
• Chevrolet Sierra 1500, Silverado 1500, Tahoe
• GMC Sierra 1500, Yukon, Yukon XL

• Replaces worn or warped rotors causing brake pulsation
• Addresses rotor corrosion and surface rust issues
• Improves heat dissipation to reduce brake fade
• Restores proper rotor thickness for safe braking
• Eliminates uneven pad wear due to rotor surface imperfections

Installation Notes and Tips

Ensure the rotor thickness is measured before installation; replace if below the discard thickness of 30 mm. Clean the hub surface to prevent runout and ensure proper rotor seating. Use the six 16 mm bolt holes to secure the rotor, matching the 139.7 mm bolt circle diameter. This rotor is non-directional, allowing installation on either side of the vehicle. Verify compatibility with your specific Cadillac, Chevrolet, or GMC model before installation.

Quality Assurance

Dynamite Friction rotors undergo rigorous quality control to meet OEM specifications. The rust-resistant coating on the rotor hat enhances longevity and performance. While no specific warranty information is provided, the DFC GEOSPEC Coated Rotor line is designed to maintain consistent braking performance under demanding conditions.
