Product Details

DFC Complete Brake Kits are built to simplify rear brake service by combining the rotor, pad, and hardware components needed for a single axle repair. The GEOSPEC rotor coating is designed to resist rust better than conventional paint or zinc finishes, while the machined cast-iron rotor construction follows OEM-style specifications for durability and stability. The 5000 Advanced pads are formulated for consistent friction, and the hardware kit addresses worn or corroded brake hardware that can contribute to noise and uneven wear. This part number 4512-21042 is a direct rear brake solution for Kia Spectra and Kia Spectra5 owners looking for a service kit with matched components.

What This Kit Helps Address

• Brake noise from worn pads or fatigued hardware
• Rust buildup on rear rotors
• Uneven rear brake wear
• Reduced stopping consistency from aged friction material
• Excess caliper movement caused by worn hardware

Installation Notes

Compatible With 2004-2006 Kia Spectra, rear; 2005-2006 Kia Spectra5, rear; 2007-2009 Kia Spectra, rear; and 2007-2009 Kia Spectra5, rear. Before installation, inspect calipers, slides, and brake fluid condition, and confirm rotor and pad surfaces are clean and free of contamination. The dry rotor finish is ready for installation, and the non-directional machining helps support a smoother bed-in process after service. Part number 4512-21042 should be matched to the rear axle application only.
