Product Details

DFC’s GEOSPEC rotor and 5000 Advanced pad combination is built for rear axle service where consistent stopping performance and clean installation matter. The rotors are machined to tight tolerances, balanced on vented designs, and inspected against critical OE specifications. The pads use a friction formulation developed for modern vehicle braking requirements, with post-curing and scorching applied to support stable performance from the first stop. This part number, 4502-52026, is a practical choice for rear brake work on GM mid-size and full-size sedan applications, including Chevrolet Impala and Pontiac Grand Prix models.

Common Problems This Kit Can Address

• Rear brake pulsation from worn or uneven rotors
• Brake noise caused by aged pads or degraded shims
• Reduced stopping performance from worn friction material
• Rust buildup on exposed rotor surfaces
• Longer service time from oil-coated replacement rotors

Installation Notes

Verify rear axle fitment by year, make, model, and VIN notes before ordering. This kit is listed for rear position only, and some 2005 Chevrolet Impala and 2005 Chevrolet Monte Carlo applications require chassis/VIN verification. The rotors are shipped dry and ready to install, which helps reduce prep time during a standard rear brake job. Follow proper brake service procedures, clean all mating surfaces, and bed the pads according to the vehicle manufacturer’s recommendations.

Quality Assurance

DFC GEOSPEC rotors are manufactured to OE specifications and each rotor is covered by a 12-month warranty against defects in material and workmanship. The 5000 Advanced pads are post-cured, scorched, and assembled with premium shims to support consistent friction performance and improved NVH characteristics.
