Dynamic Friction 4302-21012 Disc Brake Kit - Rear

Brake Kit Overview

Dynamic Friction 4302-21012 is a rear disc brake kit built for Kia compact applications that need matched rotors and ceramic pads in one service package. It combines DFC GEOSPEC coated rotors with 3000 Ceramic Brake Pads for consistent braking performance and corrosion protection.

Key Features

• Fits 2010-2013 Kia Forte, rear.
• Fits 2010-2013 Kia Forte Koup, rear.
• Fits 2012-2013 Kia Forte5, rear.
• DFC GEOSPEC rotors use a silver-gray protective coating to resist rust.
• Rotors are processed dry and ready to install without additional preparation.
• 3000 Ceramic Brake Pads are formulated for low dust, fade resistance, and stable friction across a wide temperature range.
• Post-cured pads and scorched surfaces help reduce break-in time and improve initial stopping response.
• Premium rubber-steel-rubber shims are used to improve noise, vibration, and harshness control.

Detailed Description

Part number 4302-21012 is a Dynamic Friction brake service kit that pairs coated rotors with ceramic pads for rear brake service on the Kia Forte, Kia Forte Koup, and Kia Forte5. The GEOSPEC rotor finish is engineered to fight corrosion better than conventional paint or zinc coatings, while the non-directional machined surface supports even pad bed-in and smoother braking. The 3000 Ceramic Brake Pads are built for passenger and light-duty truck use, with stable friction characteristics and low copper content for compliance-focused applications. This kit is a practical choice when you want rotor and pad components matched for the same service interval. Part number 4302-21012 is also referenced for the same application as a DFC brake kit solution.

What It Helps Solve

• Brake noise caused by worn pads or uneven rotor surfaces.
• Reduced stopping performance from heat-affected friction material.
• Rust buildup on exposed rotor surfaces.
• Longer service time caused by cleaning oil-coated replacement rotors.
• Inconsistent pedal feel from mismatched brake components.

Installation Notes and Tips

Compatible with rear brake service on the listed Kia applications only. The rotors are shipped dry and ready for installation, which reduces prep time before assembly. For best results, follow standard brake service procedures, inspect related wear items, and bed in the pads according to the friction material manufacturer’s recommendations.

Quality Assurance

DFC GEOSPEC rotors are machined to tight tolerances, inspected for critical dimensions, and finished to OE-style specifications for durability and stability. The brake pads are post-cured and scorched to support consistent friction performance from the first stop. Part number 4302-21012 is backed by a 12-month warranty against defects in material and workmanship on the rotor components.
