Detailed Description

DFC Friction builds this brake kit to match OE-style requirements for modern vehicles that depend on consistent friction, stable pedal feel, and quiet operation. The 4514-21031 kit is engineered for Hyundai Sonata and Kia K5 drivers who need a complete brake service package with rotors, pads, and hardware selected for the same axle positions. The DFC Geospec rotor coating helps resist rust while the machined cast-iron rotor design is finished to tight tolerances for reliable fit and smooth stopping performance. The DFC 5000 Advanced pads are formulated for controlled friction, and the hardware kit is designed to restore proper caliper movement and spring tension.

This part number 4514-21031 is a practical choice for a Hyundai Sonata brake kit or Kia K5 brake kit when the goal is to replace worn braking components with a matched set. It is also a strong search match for buyers looking for a front and rear brake kit for 2020-2026 Hyundai Sonata or 2021-2024 Kia K5.

What It Helps Address

• Brake noise from worn pads or fatigued hardware
• Uneven pad wear caused by corroded or weakened hardware
• Rotor rust and surface corrosion on daily-driven vehicles
• Reduced braking consistency from worn friction materials
• Longer service time from cleaning oil-coated replacement rotors

Installation Notes and Tips

Inspect calipers, slides, and mounting points before installation. Clean all hub and bracket surfaces, and follow the vehicle manufacturer’s torque specifications during assembly. The rotors are shipped dry and ready to install, so no oil removal step is required. Proper bedding-in after installation helps establish even pad transfer and consistent braking feel.

Quality Assurance

DFC states that the brake pads are post-cured and scorched for stable performance, while the rotors are machined to OE specifications and inspected for critical dimensions and balance. The GeoSpec rotors include a 12-month warranty against defects in material and workmanship.
