DFC GEOSPEC Coated Rotor and Pad Line

The DFC GEOSPEC Coated Rotors with 5000 Advanced Brake Pads - Ceramic and Hardware line is built for drivers who want a complete rear brake solution without mixing components from different sources. The rotors are machined to tight tolerances, finished with a non-directional surface for more even pad bed-in, and inspected for balance and critical dimensions. The pads are formulated for stable friction performance and reduced initial break-in, while the hardware kit uses PTFE coating, vulcanized rubber, and stainless steel for consistent caliper movement.

What This Brake Kit Helps Address

• Rear brake noise during stops
• Uneven pad wear from fatigued hardware
• Brake rotor rust and surface corrosion
• Vibration or harshness during braking
• Longer installation time from unprepared rotors
