Dynamite Friction 4504-03039 Disc Brake Kit - Front and Rear

Brake Kit for Kia Optima

The Dynamite Friction DFC GEOSPEC Rotors with 5000 Advanced Brake Pads kit combines coated brake rotors and matched friction material for service on select Kia Optima applications. It is built for drivers replacing worn front and rear brake components on 2011-2015 Kia Optima models, with a separate note for 2014-2015 vehicles using a manual parking brake.

• Disc brake kit with rotors and pads in one package
• DFC GEOSPEC coated rotors with a silver-gray corrosion-resistant finish
• Rotors are processed dry and ready to install
• G3000/G11H18 cast iron rotor specification for OE-style durability and stability
• Non-directional rotor finish for more even pad bed-in and smoother braking
• 5000 Advanced Brake Pads are post-cured and scorched to reduce initial break-in time
• Premium rubber-steel-rubber shims help improve noise, vibration, and harshness control

Product Details

Part number 4504-03039 is part of DFC’s GEOSPEC rotor and 5000 Advanced Brake Pad line, a service kit approach that pairs coated rotors with application-specific pads. For Kia Optima brake service, this setup supports a cleaner installation process because the rotors arrive dry and do not require oil removal before mounting. The rotor machining and inspection process is aimed at consistent dimensions, balance, and OE-spec fitment behavior. Part number 4504-03039 is a practical choice for a Kia Optima brake job when replacing both rotors and pads at the same time.

What It Helps Address

• Brake pulsation from worn or uneven rotors
• Squeal or vibration from aged pad and rotor surfaces
• Extended stopping distance caused by worn friction material
• Corrosion on exposed rotor surfaces
• Time lost sourcing pads and rotors separately for a Kia Optima brake repair

Installation Notes

Fits 2011-2015 Kia Optima, front and rear. Fits 2014-2015 Kia Optima, front and rear, manual parking brake applicable on this Disc Brake Rotor. Verify axle position and parking brake configuration before installation. The rotors are supplied dry and ready to install, and the non-directional finish supports pad bed-in after service. Part number 4504-03039 should be matched to the vehicle’s brake configuration before ordering.

Quality Assurance

DFC states that each brake pad is 100% post-cured and scorched for stable friction performance, and that the rotors undergo machining, balance correction where needed, and 100% inspection of critical dimensions. GEOSPEC rotors carry a 12-month warranty against defects in material and workmanship.
