Dynamic Friction 7004-21007 Disc Brake Rotor Set - Front and Rear

Performance brake rotor set

Dynamic Friction 7004-21007 is a drilled and slotted brake rotor set built for drivers who want stronger initial bite and more consistent braking performance. It is compatible with 2017-2020 Kia Cadenza applications at the front and rear positions.

Key features

• Drilled and slotted design helps increase pad bite and improve wet-weather braking response.
• Drilled holes help reduce heat buildup during repeated stops.
• Slots clear brake dust and road debris while helping reduce pad glazing.
• G3000/G11H18 cast iron construction is engineered to match OEM durability and stability targets.
• Non-directional finish supports faster pad bed-in and smoother, quieter stops.
• Each rotor is inspected for balance and critical dimensions to support OE-level fit and function.

Detailed description

The Dynamic Friction 7004-21007 rotor set is part of the DFC Rotors-Drilled and Slotted-Silver line, which focuses on performance-oriented braking with OE-spec engineering. These rotors use a drilled and slotted surface to improve pad contact, manage heat, and keep the braking surface cleaner under demanding conditions. For Kia Cadenza owners, this part number offers a direct replacement option for 2017-2020 vehicles in front and rear applications.

DFC machines each casting to tight tolerances and finishes the surface with a non-directional pattern to promote even pad transfer during break-in. The rotors are also 100% inspected, with balance correction performed when needed, to help maintain consistent braking quality. If you are searching for a 7004-21007 brake rotor set for a Kia Cadenza, this part is built around durability, reliability, and stable braking performance.

What it helps solve

• Brake fade from excess rotor heat
• Reduced stopping response in wet conditions
• Pad glazing caused by heat and debris buildup
• Uneven pad bed-in and brake noise
• Rotor vibration related to balance or machining variation

Installation notes and tips

Verify rotor size and brake package details against your vehicle before installation. Clean the hub mounting surface thoroughly and inspect pads, calipers, and hardware condition before fitting the new rotors. Proper pad break-in after installation helps the non-directional finish perform as intended.

Quality assurance

DFC states that these rotors are manufactured to OE specifications and individually inspected for critical dimensions and balance. Part number 7004-21007 is backed by a 12 month or 12,000 mile limited warranty against defects in material and workmanship.
