Product Details

DFC’s GEOSPEC rotor line is built around corrosion protection and installation efficiency. The coated rotor surface helps resist rust better than conventional paint or zinc finishes, while the dry packaging means the parts are ready for installation without extra prep. The 5000 Advanced pads are developed for axle-specific friction needs and are assembled with shims that support quieter operation. Together, these components provide a matched rear brake solution for Lexus GS350 rear brake replacement, Lexus IS350 rear brake service, and Lexus RC350 rear brake maintenance.

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

Common Problems This Kit Can Address

• Rear brake pulsation from worn or uneven rotors
• Rust buildup on exposed rotor surfaces
• Squeal or vibration during braking
• Reduced stopping performance from worn pads
• Longer service time caused by rotors that require cleaning before installation
