DFC GEOSPEC Rotors with 5000 Pads

The DFC GEOSPEC rotor line is engineered to match OE specifications for fit, balance, and braking consistency. Each rotor is machined to tight tolerances, finished with a non-directional surface, and inspected for critical dimensions and balance on vented applications. The coated surface helps resist rust better than conventional paint or zinc finishes, while the dry packaging avoids the need to clean oil from the rotor before installation. The 5000 Advanced Brake Pads are formulated for stable friction performance, reduced initial break-in, and improved noise and vibration control through premium shims. This makes the DFC 4502-80110 a practical rear brake service choice for Mazda 3 and Mazda 3 Sport owners seeking a complete rotor-and-pad replacement.

Common Reasons to Replace

• Rear brake noise, squeal, or vibration
• Rust buildup on rear rotors
• Reduced braking response or uneven stopping feel
• Pad wear that has reached service limits
• Brake pulsation from worn or uneven rotor surfaces

Installation Notes

Verify that the vehicle is a Mexico-built 2017-2018 Mazda 3 or Mazda 3 Sport with rear brakes and without an electric parking brake before ordering. Clean the hub surface before installation, follow the vehicle manufacturer’s torque specifications, and bed the pads in according to standard brake service procedure. The rotor coating is removed naturally by the pad friction during normal use.

Quality Assurance

Each rotor is 100% inspected after machining to confirm critical attributes and OE-spec compliance. DFC includes a 12-month warranty against defects in material and workmanship on the rotors. Part number 4502-80110 is built as a complete rear brake service kit for consistent fitment and dependable service.
