Product Line Details

DFC Brake Rotors - GEOSPEC Coated is Dynamite Friction’s coated rotor line for drivers who want a replacement rotor with a protective surface treatment. The coating helps reduce rust on non-friction areas while maintaining the braking surface needed for normal pad contact. This makes the line a practical choice for daily-driven Chevrolet Bolt EV and Chevrolet Cruze front brake service.

What It Helps Address

• Front rotor wear from normal braking use
• Brake pulsation caused by rotor surface irregularity
• Rust buildup on exposed rotor areas
• Noise from worn or uneven front rotors
• Service replacement for Chevrolet Bolt EV, Cruze, Sonic, and Volt front brakes

Installation Notes

Verify rotor diameter, trim, and brake package before ordering, especially on Chevrolet Cruze applications with 276mm front rotors, 2LT trim, Mexico build notes, or upgraded front pads with spreader spring tabs. Replace rotors in axle pairs and inspect pads, caliper hardware, and hub surfaces during service. This part cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application.

Quality Assurance

Dynamite Friction’s GEOSPEC coated rotor line is built for consistent replacement fitment and corrosion-resistant surface protection on the non-friction areas of the rotor.
