Product Line Details

The DFC GEOSPEC rotor line is engineered to OE specifications using G3000/G11H18 cast iron, tight machining tolerances, balance inspection on vented rotors, and final inspection of critical dimensions. The 5000 Advanced pad line is formulated for stable friction performance and consistent pedal response, while the hardware kit is built to restore proper spring tension and caliper movement during brake service.

What This Kit Helps Address

• Rear brake noise from worn pads or fatigued hardware
• Rust buildup on exposed rotor surfaces
• Uneven rear braking feel
• Extended stopping distance caused by worn friction components
• Caliper movement issues related to corroded or weakened hardware

Installation Notes and Tips

Fits 2015-2020 Chevrolet Colorado, rear. Fits 2015-2020 GMC Canyon, rear. Before installation, confirm rear axle brake configuration and compare the existing rotor and pad setup to part number 4512-48145. The dry rotor coating is designed to be removed by normal pad contact during break-in, so no extra rotor prep is required. Follow standard brake service procedures, clean the hub mounting surface, and torque all fasteners to factory specifications.
