Product Line Details

The DFC GEOSPEC rotor and 5000 Advanced pad combination is designed as a service kit for drivers who want OE-style fitment, corrosion protection, and consistent braking response in one package. The coated rotor surface is intended to resist rust better than conventional painted or zinc-coated finishes, while the pad formulation is engineered for stable friction and smoother engagement after installation.

This part cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application.

Installation Notes

Before installation, confirm rear disc brake configuration and match the vehicle notes shown above, including TRW rear disc brake applications and Mexico-built Astra listings. Inspect calipers, slides, and mounting points for wear before assembling the new kit. The rotors are processed dry and ready to install, which helps reduce prep time during a rear brake job.

Quality Assurance

DFC GEOSPEC rotors are machined to tight tolerances, finished with a non-directional surface for more even pad bed-in, and inspected for balance and critical dimensions. The rotors carry a 12-month warranty against defects in material and workmanship.
