Product Line Details

DFC Complete Brake Kits are organized to simplify brake service by combining the main wear components needed for a single axle. The GEOSPEC rotor line focuses on dry, ready-to-install coated rotors that resist rust better than conventional painted or zinc-coated finishes, while the 5000 Advanced pad line uses ceramic friction material tuned for stable performance and quieter operation.

Detailed Description

4512-80064 is engineered for rear brake service on Mazda 3 and Mazda 3 Sport models listed in the fitment data. The rotors are cast to G3000/G11H18 specifications, machined to tight tolerances, and inspected for critical dimensions and balance. The pads are post-cured and assembled with premium shims to help maintain consistent pedal feel and reduce brake noise. This makes the kit a practical choice for a Mazda 3 rear brake rotor and pad replacement, a Mazda 3 Sport rear brake service, or a complete rear brake overhaul with coated rotors and hardware.

Common Problems This Kit Can Address

• Rear rotor rust and surface corrosion
• Brake noise from worn pads or fatigued hardware
• Uneven rear pad wear
• Reduced braking consistency from aged friction material
• Longer service time caused by uncoated rotors that require extra prep

Installation Notes and Tips

Fits 2004-2013 Mazda 3, rear. Fits 2010-2013 Mazda 3 Sport, rear. Verify rotor size and rear brake configuration before installation, and inspect caliper slides and mounting points during service. The coated rotor surface is ready to install dry; the coating will wear away naturally in the pad contact area during normal braking. For best results, follow the vehicle manufacturer’s brake bedding procedure after installation.

Quality Assurance

DFC GEOSPEC rotors are manufactured to OE-style specifications, then 100% inspected for critical attributes before release. Vented rotors are electronically mill-balanced when required, and each rotor includes a 12-month warranty against defects in material and workmanship. Part number 4512-80064 is built to support dependable rear brake service on Mazda 3 and Mazda 3 Sport applications.
