Product Details

DFC GEOSPEC Rotors with 5000 Advanced Brake Pads are engineered for drivers who need a rear brake service kit that matches factory-style fit and braking behavior. The coated rotors resist rust better than conventional painted or zinc-coated alternatives, while the dry finish eliminates the need to clean off oil before installation. The pads are formulated for consistent friction, with post-curing and scorching steps that help reduce initial break-in time. This kit is a practical choice for rear brake service on 2014-2016 Kia Cadenza, 2015-2019 Hyundai Sonata, 2016-2017 Hyundai Tucson, and 2016-2020 Kia Optima applications. Part number 4502-03118 is also a useful reference when searching for a rear brake kit for Kia Optima rear brake replacement or Hyundai Sonata rear disc brake service.

What This Kit Helps Address

• Rear brake noise, squeal, or vibration
• Rust buildup on exposed rotor surfaces
• Uneven or worn rear brake pad and rotor surfaces
• Longer stopping distances caused by worn brake components
• Brake service needs on Hyundai Sonata, Kia Optima, Kia Cadenza, and Hyundai Tucson rear axles

Installation Notes and Tips

Fits 2016-2020 Kia Optima, rear; 2015-2019 Hyundai Sonata, rear; 2016-2017 Hyundai Tucson, rear; and 2014-2016 Kia Cadenza, rear. Some applications note manual parking brake use on the rear rotor, and certain Kia Optima fitments reference 305mm or 320mm front disc configurations.

Quality Assurance

Each rotor is machined to tight tolerances, finished with a non-directional surface, and inspected for critical dimensions and balance where applicable. DFC states that every rotor is checked against OE specifications, and the kit includes a 12-month warranty against defects in material and workmanship.
