Product Line Details

DFC Complete Brake Kits are organized to simplify brake service by combining the main wear components needed for a rear brake job. The GEOSPEC rotor line is dry processed and dry shipped, so the rotors are ready to install without cleaning off oil-based packaging residue. The 5000 Advanced pad line is formulated for stable friction performance and consistent pedal feel, while the hardware kit addresses worn or corroded brake hardware that can affect caliper movement and pad wear.

• Uneven braking feel caused by worn rotor finish or pad material

Installation Notes
