Common Brake Service Issues

• Rear brake noise from worn pads or fatigued hardware
• Rust buildup on exposed rotor surfaces
• Uneven braking feel from worn rotor finish
• Reduced stopping consistency after pad wear
• Excess caliper movement caused by aged hardware

Installation Notes

Before ordering, verify rear axle fitment and electric parking brake configuration against the vehicle listing. The rotors are shipped dry and ready to install, which reduces prep time during service. For proper results, clean the hub mounting surface, inspect caliper slides, and follow the vehicle manufacturer’s brake service procedure during installation.

Quality Assurance

DFC machines the rotors to tight tolerances, applies a non-directional finish, and inspects critical dimensions to OE specifications. Vented rotors are balance-checked and corrected when needed. The rotors carry a 12-month warranty against defects in material and workmanship. Part number 4512-21052 is built as a complete rear brake service solution for Kia Forte, Kia Optima, and Hyundai Sonata applications.
