Product Details

Part number 4502-80063 is engineered as a complete rear brake service solution for Mazda 3 and Mazda 3 Sport models. The GEOSPEC rotors are machined to tight tolerances, balanced where required, and inspected for critical dimensions to meet OE specifications. The 5000 Advanced pads are formulated for stable friction performance, with scorch treatment to reduce initial break-in time and shims that help control noise, vibration, and harshness. This part cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application.

What This Brake Kit Helps Address

• Rear brake pulsation from worn or uneven rotors
• Brake noise caused by aged pads or poor pad-to-rotor contact
• Rust buildup on exposed rotor surfaces
• Reduced stopping performance from worn rear brake components
• Extended service time when replacing rotors and pads separately

Installation Notes and Tips
