Dynamic Friction 4502-21083 Disc Brake Kit - Rear

Brake Kit Overview

This DFC disc brake kit combines GEOSPEC coated rotors with 5000 Advanced brake pads for a rear brake service on select Genesis and Kia applications. It is built for buyers looking for an OE-style brake kit with corrosion protection, stable friction, and a cleaner installation process.

Key Features

• GEOSPEC coated rotors with a silver-gray finish that resists rust better than conventional paint or zinc coatings.
• Dry-processed rotors arrive ready to install without additional preparation.
• Non-directional rotor finish supports more even pad bed-in and smoother braking.
• 5000 Advanced brake pads are post-cured for stable friction performance.
• Scorched pad surfaces reduce initial break-in time and improve first-stop response.
• Rubber-steel-rubber shims help reduce noise, vibration, and harshness.

Detailed Description

Part number 4502-21083 is a rear disc brake kit engineered for Fits 2021-2022 Genesis G90, rear and Fits 2019-2020 Kia K900, rear. The kit pairs coated rotors with advanced friction pads to support consistent braking performance, quieter operation, and improved corrosion resistance in everyday service. DFC designs the rotor and pad components to meet OE-style expectations for durability, reliability, and stability, while the machining and coating process helps reduce prep time during brake work. Part number 4502-21083 is a practical choice for Genesis G90 and Kia K900 rear brake replacement when you want matched rotor and pad components in one service kit.

Common Issues This Kit Addresses

• Brake noise during normal stopping.
• Rust buildup on exposed rotor surfaces.
• Uneven pad bedding after rotor replacement.
• Reduced initial braking response after service.
• Brake vibration related to worn rotor surfaces.

Installation Notes and Tips

Fits 2021-2022 Genesis G90, rear and Fits 2019-2020 Kia K900, rear. Verify rotor style and rear brake configuration before ordering, especially on applications with original design aluminum hat front rotors noted in the fitment data. The rotors are shipped dry and ready for installation, so no oil removal step is required. Follow standard brake service procedures, clean the hub mounting surface, and bed the pads according to the vehicle service process after installation.

Quality Assurance

DFC states that the rotors are machined to OE specifications and inspected for critical dimensions and balance where applicable. The rotors carry a 12-month warranty against defects in material and workmanship.
