The Story
Rear Brake Kit for Mazda 3 and CX-30
The Dynamite Friction DFC Geospec Rotors with 5000 Advanced Brake Pads includes Hardware kit is a rear disc brake service kit built for select Mazda applications. Part number 4512-80367 combines coated rotors, advanced friction pads, and matching hardware for a complete rear brake refresh.
Key Features
- Rear disc brake kit with rotors, pads, and hardware
- DFC 5000 Advanced Brake Pads with post-cured friction material
- Scorched pad surface to reduce initial break-in time
- Premium rubber-steel-rubber shims for improved noise, vibration, and harshness control
- GeoSpec coated rotors with a silver-gray corrosion-resistant finish
- Dry-processed rotors arrive ready to install
- Non-directional rotor finish for more even pad bed-in and smoother braking
- Machined to OE-style tolerances and 100% inspected for critical dimensions
Product Details
DFC 5000 Advanced Brake Pads are formulated for consistent friction performance and are assembled with premium shims to help reduce brake noise and vibration. The GeoSpec rotors use G3000/G11H18 cast iron specification and a protective coating that helps resist rust while eliminating the need to clean oil from the rotor before installation. Part number 4512-80367 is a practical choice for drivers servicing the rear brakes on a Mazda 3, Mazda 3 Sport, or Mazda CX-30.
Compatible With 2019-2025 Mazda 3, rear; 2019-2025 Mazda 3 Sport, rear; 2020-2022 Mazda CX-30, rear; and 2023-2025 Mazda CX-30, rear with 265mm rear disc. This part cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application.
Common Brake Service Issues
- Rear brake noise, squeal, or vibration
- Uneven pad wear or reduced pad contact
- Rust buildup on rotor surfaces
- Longer stopping distances from worn friction components
- Brake pulsation caused by rotor wear or thickness variation
Installation Notes
Fits 2019-2025 Mazda 3, rear. Fits 2019-2025 Mazda 3 Sport, rear. Fits 2020-2022 Mazda CX-30, rear. Fits 2023-2025 Mazda CX-30, rear, 265mm rear disc. Clean the hub face before installation, verify rotor orientation and pad fitment, and follow the vehicle manufacturer’s brake service procedure for bedding-in the new pads and rotors.
Quality Assurance
DFC machines each rotor to tight tolerances, performs 100% inspection of critical attributes, and balances vented rotors as needed. The rotors include a 12-month warranty against defects in material and workmanship. Part number 4512-80367 is built to OE-style specifications for durability, reliability, and stable braking performance.
