Product Details

DFC’s GEOSPEC rotor line uses a silver-gray protective coating that is applied before shipping, so the rotors arrive ready for installation without oil removal or extra cleaning. The rotors are machined to tight tolerances, finished with a non-directional surface, and inspected for balance and critical dimensions to meet OE specifications. The 5000 Advanced pads are post-cured and scorched to reduce break-in time, while the shim design supports quieter operation. This rear brake kit is a practical choice for Dodge Challenger rear brake replacement, Dodge Charger rear brake service, Chrysler 300 rear brake repair, and Dodge Magnum rear brake maintenance.

Common Problems This Kit Can 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
• Extended stopping distance from worn friction material
• Uneven braking feel during rear brake service
