• Hardware kit uses PTFE coating, vulcanized rubber, and stainless steel

Product Details

The DFC GEOSPEC rotor line is engineered to OE specifications using G3000/G11H18 cast iron, then machined to tight tolerances and inspected for critical dimensions and balance. For rear brake service on the Mazda 6 and Mazda Protege, this helps deliver consistent pedal feel, quieter stops, and reliable rotor stability. The 4512-99052 kit is a practical choice for a rear brake job where corrosion protection, fitment accuracy, and pad-to-rotor matching matter.

DFC 5000 Advanced Brake Pads are formulated for modern vehicle braking demands and assembled with premium shims to help reduce brake noise. The hardware kit is designed to replace worn or fatigued components that can contribute to uneven wear, caliper movement, and brake noise over time.

What This Kit Helps Address

• Rear brake noise during stops
• Rust buildup on exposed rotor surfaces
• Uneven or premature rear pad wear
• Reduced braking smoothness after rotor wear
• Brake hardware fatigue, corrosion, or loss of spring tension

Installation Notes

Install on the rear axle only. The rotors are shipped dry and ready to install, which can reduce prep time during service. Clean the hub mounting surface before installation, verify caliper operation, and follow standard brake bedding procedures after installation. Confirm vehicle application by year, make, model, and rear position before ordering.

Quality Assurance

Each DFC GeoSpec coated rotor is 100% inspected after machining, including balance checks on vented rotors when required. Rotors are covered by a 12-month warranty against defects in material and workmanship. Part number 4512-99052 is built to meet OE-style expectations for rear brake service on the listed Mazda applications.
