Product Details

The DFC GEOSPEC rotor design is machined to tight tolerances and built to OE specifications for durability, stability, and reliable braking performance. The coated surface helps resist rust better than conventional paint or zinc finishes, while the dry shipping process eliminates the need to clean oil from the rotor before installation. The 5000 Advanced ceramic pads are post cured and scorched to reduce initial break-in time and deliver consistent friction from the first stop. This rear brake kit for Hyundai Sonata models is a practical choice for drivers replacing worn rear rotors, pads, and hardware at the same time. Part number 4512-03123 is also a useful reference when ordering the correct rear brake kit for these Sonata applications.

Common Brake Service Issues

• Rear brake noise, squeal, or vibration
• Rust buildup on exposed rotor surfaces
• Uneven or reduced rear braking performance
• Premature pad wear from fatigued hardware
• Longer stopping distances caused by worn friction components

Installation Notes

Verify rear fitment by year and production date before installation: 2005 Sonata from 4/05, 2008 Sonata to 2/08, and 2006-2007 Sonata for the rear axle. Clean the hub mounting surface, inspect caliper condition, and follow proper pad bedding procedures after installation. The rotors are ready to install as shipped, and the non-directional finish is intended to help promote even pad contact during break-in.

Quality Assurance

Each rotor is 100% inspected for critical dimensions and balance, with vented rotors corrected as needed during the mill-balance process. DFC states that every rotor is checked to meet OE specifications, and the rotors carry a 12-month warranty against defects in material and workmanship. Part number 4512-03123 identifies this rear brake kit for Hyundai Sonata service applications.
