Product Details

Part number 4302-80040 is part of the DFC GEOSPEC Rotors with 3000 Ceramic Brake Pads line, a brake service kit focused on OE-style fit, corrosion protection, and stable braking behavior. The rotors use a coated silver-gray finish to resist rust better than conventional paint or zinc coatings, while the ceramic pads are post-cured and scorched to help deliver consistent friction from the first stop. Premium rubber-steel-rubber shims are used to improve noise, vibration, and harshness control. This part number 4302-80040 is a direct front brake solution for Mazda CX-3 and Mazda 3 models listed in the fitment data.

This part cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application.

Common Brake Issues This Kit Can Address

• Brake pulsation from worn or uneven front rotors
• Excessive brake dust from older pad material
• Squealing or vibration during normal braking
• Reduced stopping consistency from heat-affected pads
• Rust buildup on exposed rotor surfaces

Installation Notes and Tips

Confirm your vehicle’s build details before ordering, especially for 2017-2018 Mazda 3 and Mazda 3 Sport models, which must be Japan built and exclude electric parking brake applications. The rotors are shipped dry and ready for installation, so no oil cleaning step is required. For best results, follow a proper brake bed-in procedure after installation and inspect caliper condition, slide pins, and brake fluid before completing the job.

Quality Assurance

Each DFC GEOSPEC rotor is machined to tight tolerances, finished with a non-directional surface, and inspected for critical dimensions and balance. The rotors carry a 12-month warranty against defects in material and workmanship.
