Product Details

Part number 4502-68014 is part of the DFC Complete Brake Kits lineup, which packages matched rotors and pads for a single rear-axle service. For Infiniti Q45 and Infiniti M45 rear brake service, this kit brings together coated DFC GEOSPEC rotors and DFC 5000 Advanced pads to support smoother stops, faster pad bed-in, and improved resistance to rotor rust compared with conventional painted or zinc-coated finishes. The rotors are machined to tight tolerances, balanced where required, and inspected against OE specifications. The pads are formulated for stable friction and reduced initial break-in time.

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

Common Brake Issues It Can Address

• Rear brake pulsation from worn or uneven rotors
• Brake noise caused by pad wear or rotor surface condition
• Reduced stopping consistency from aged friction material
• Visible rotor rust on exposed braking surfaces
• Longer service time from rotors that require extra prep before installation

Installation Notes

Compatible With rear axle service on 2002-2006 INFINITI Q45 and 2003-2004 INFINITI M45. The rotors are shipped dry and ready for installation, which eliminates the need to clean off oil before assembly. Follow standard brake service procedures, verify rotor orientation and pad fitment before final assembly, and complete a proper bed-in procedure after installation for even transfer layer formation.

Quality Assurance

DFC GEOSPEC rotors are manufactured to OE specifications, finished with a non-directional surface, and 100% inspected for critical dimensions and balance on vented applications. Each rotor includes a 12-month warranty against defects in material and workmanship. The brake pads are post-cured, scorched, and assembled with premium shims to support stable friction and NVH control.
