Key Features

• Complete disc brake kit with coated rotors, ceramic brake pads, and hardware
• DFC GEOSPEC coated rotors with a silver-gray finish that resists rust better than conventional paint or zinc coatings
• Dry-processed rotors ship ready to install with no oil removal or prep cleaning
• G3000/G11H18 cast iron rotor construction matched to OEM specifications
• Non-directional rotor finish for more even pad bed-in and quieter stopping
• DFC 5000 Advanced pads are post-cured and scorched for stable friction and reduced break-in time
• Premium rubber-steel-rubber shims help reduce noise, vibration, and harshness
• Hardware kit uses PTFE coating, vulcanized rubber, and stainless steel for OE-style fit and function

Product Details

DFC’s GEOSPEC rotor line focuses on corrosion protection, machining accuracy, and consistent braking feel. Each rotor is machined to tight tolerances, finished with a non-directional surface, and inspected for critical dimensions and balance on vented applications. The 5000 Advanced ceramic pads are formulated for stable friction across a wide range of driving conditions, while the included hardware is designed to restore proper caliper movement and spring tension. Part number 4514-03074 is a practical choice for drivers servicing a Hyundai Sonata or Kia Optima brake system and looking for a complete rotor, pad, and hardware package.

Common Brake Issues This Kit Can Address

• Brake noise from worn pads or fatigued hardware
• Uneven pad wear caused by corroded or weak hardware components
• Rotor rust on exposed surfaces
• Longer stopping distances from worn friction material
• Vibration or rough brake feel from rotors that no longer meet OE tolerances
