Product Details

DFC GEOSPEC Rotors with 5000 Advanced Brake Pads are engineered as a service kit for rear brake replacement on select 2013-2022 Kia and Hyundai vehicles. The rotor coating is designed to resist corrosion better than conventional paint or zinc finishes, while the machined surface and balance inspection support consistent braking performance. The pad compound is formulated for stable friction, and the shims are used to help reduce brake noise and harshness. This kit is a practical choice for rear brake service on a Kia Optima rear brake job, Hyundai Sonata rear brake replacement, or Kia Forte rear disc brake maintenance.

What This Kit Helps Address

• Rear brake noise, squeal, or vibration
• Rust buildup on exposed rotor surfaces
• Uneven or inconsistent braking feel
• Extended brake service time from uncoated rotors
• Rear pad and rotor wear on electric parking brake-equipped vehicles
