Product Details

DFC designed this brake service kit to match OE-style form, fit, and function for heavy-duty rear brake applications. The GEOSPEC rotors use G3000/G11H18 cast iron and are machined to tight tolerances, then inspected for balance and critical dimensions. The 5000 Advanced pads are scorched to reduce initial break-in and assembled with premium shims to help control brake noise, vibration, and harshness. This kit is a practical choice for Chevrolet Express 3500 rear brake replacement and GMC Savana 3500 rear brake replacement where consistent stopping performance and corrosion protection matter.

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

Installation Notes

Inspect calipers, slides, and mounting surfaces before installation. Clean the hub face, verify rotor seating, and follow the vehicle manufacturer’s torque specifications. Because the rotors are shipped dry, no oil removal is required before installation. Use proper bedding procedures after installation to help establish even pad transfer.

Quality Assurance

Each DFC GEOSPEC rotor is 100% inspected after machining, and vented rotors are balance-checked and corrected when needed. The rotors carry a 12-month warranty against defects in material and workmanship.
