Product Details

DFC GEOSPEC Rotors with 5000 Advanced Brake Pads are engineered as a service kit for drivers who want matched brake components in one box. The rotors are machined to tight tolerances, inspected for critical dimensions, and balanced where required. The pad formulation is processed to reduce initial break-in time and deliver stable friction from the first stop. This kit is a practical choice for 2016-2019 Hyundai Sonata brake replacement, 2016-2019 Kia Optima brake replacement, and 2020 Kia Optima front and rear brake service. Part number 4504-03074 is also a useful reference when searching for a complete brake kit for these vehicles.

Common Brake Issues This Kit Can Address

• Brake pulsation caused by worn or uneven rotors
• Noise from pads with degraded shims or inconsistent friction material
• Rust buildup on exposed rotor surfaces
• Longer stopping distances from worn brake components
• Uneven pad transfer or rough brake feel during service intervals
