Product Details

DFC GEOSPEC rotors are manufactured to OEM-style G3000/G11H18 cast iron specifications and machined to tight tolerances for durability, reliability, and stable braking performance. The coated surface is designed to resist rust better than conventional paint or zinc finishes, while the dry-ready packaging eliminates the need to clean oil from the rotor before installation. The 5000 Advanced pad compound is developed for modern vehicle braking demands and is assembled with noise-reducing shims for smoother operation. This rear brake kit is a direct-fit service solution for Mazda Protege and Mazda Protege5 rear brake maintenance, including part number 4512-80056.

Common Reasons to Replace

• Rear brake noise, squeal, or vibration
• Rust buildup on rotor surfaces or hats
• Uneven pad wear or reduced braking consistency
• Brake pulsation from worn or out-of-spec rotors
• Corroded or fatigued brake hardware

Installation Notes

Rear brake service on these applications is typically completed during a standard axle brake job. Inspect calipers, slides, and parking brake components before installation, and follow proper bedding procedures after the new pads and rotors are installed. Confirm rear fitment by model year before ordering the 4512-80056 kit.

Quality Assurance

Each rotor is 100% inspected for critical dimensions and balance, with vented rotors electronically mill-balanced when required. The finished rotor set is backed by a 12-month warranty against defects in material and workmanship.
