Product Details

DFC’s 5000 Advanced pad formulation is built around stable friction performance, reduced initial break-in, and quieter operation. The pads are post-cured to help maintain consistent friction characteristics, then scorched to remove uncured bonding agents. DFC also uses premium rubber-steel-rubber shims to help reduce noise, vibration, and harshness.

The GeoSpec rotors are made to OEM-style G3000/G11H18 cast iron specifications and machined to tight tolerances with a non-directional finish for more even pad bed-in and smoother braking. The coated surface helps resist rust better than conventional paint or zinc finishes, and the dry-pack design eliminates the need to clean oil from the rotor before installation. Part number 4502-03047 is a practical rear brake service solution for Hyundai Sonata, Hyundai Azera, and Kia Optima rear brake maintenance.

What This Brake Kit Helps Address

• Rear brake noise, vibration, or harshness
• Rust buildup on exposed rotor surfaces
• Uneven or inconsistent brake feel
• Extended stopping distance caused by worn pads and rotors
• Brake service delays from rotors that require cleaning before installation

Installation Notes

Verify rear axle fitment before ordering, especially for 2009-2010 Hyundai Sonata applications noted as from 12/09. Clean all mating surfaces, inspect caliper hardware and guide pins, and follow the vehicle manufacturer’s brake service procedure. Proper pad bed-in is recommended after installation to help establish even transfer on the rotor surface.

Quality Assurance

Each DFC GeoSpec rotor is 100% inspected for critical dimensions, balance, and OE-spec compliance after machining. The rotors include a 12-month warranty against defects in material and workmanship. Part number 4502-03047 is engineered as a complete rear brake kit for dependable service on compatible Hyundai and Kia rear applications.
