DFC GEOSPEC Coated Rotor Product Line Details

The DFC GEOSPEC Coated Rotor line by Dynamite Friction focuses on providing rotors with a protective coating to resist corrosion and extend service life. This coating helps maintain rotor integrity under various driving conditions, making it suitable for vehicles such as the Buick LeSabre, Cadillac DeVille, and Chevrolet Lumina APV. The 604-45003 part number represents a rotor within this line that balances durability with precise fitment specifications.

Technical Description and Specifications

This disc brake rotor features a vented design that improves heat dissipation during braking, reducing the risk of brake fade. The nominal thickness of 26.3 mm ensures structural strength, while the discard thickness of 24.3 mm indicates the minimum safe thickness before replacement is necessary. The rotor’s 261 mm outside diameter and 70.7 mm inside diameter are matched to specific vehicle hubs, and the 5-bolt hole pattern with 14.2 mm diameter holes ensures secure mounting. The 51.1 mm height dimension is critical for compatibility with caliper assemblies on compatible models.

Compatible Vehicles and Applications

• Buick models including Century, LeSabre, and Regal
• Cadillac models such as DeVille, Eldorado, and Seville
• Chevrolet models including Lumina APV and Commercial Chassis
• Oldsmobile models like Cutlass Ciera and Delta 88
• Pontiac models including Bonneville and Grand Prix

This rotor is suitable for vehicles requiring a vented disc brake rotor with the specified dimensions and bolt pattern, commonly found in late 20th-century GM platforms.

Installation Notes and Tips

• Verify rotor dimensions and bolt pattern against vehicle specifications before installation
• Inspect caliper and brake pads for wear and replace if necessary during rotor installation
• Ensure proper torque on mounting bolts to manufacturer specifications
• Clean rotor surface to remove any protective coating residue before use
• Check for proper rotor runout to avoid vibration or uneven braking
