• Scorched pads to reduce initial break-in time
• Premium rubber-steel-rubber shims for improved NVH control
• Part number 4502-99172

DFC GEOSPEC Rotors with 5000 Pads

DFC GEOSPEC Rotors with 5000 Advanced Brake Pads are engineered as a complete rear brake service solution for 2007-2012 Lincoln Navigator and 2007-2009 Ford Expedition rear applications. The coated rotors are machined to tight tolerances, inspected for critical dimensions, and finished to support quieter, smoother stops. The pad compound is post-cured and scorched to promote stable friction performance from the first stop, while the shim design helps reduce noise, vibration, and harshness. This is a practical choice for drivers servicing rear brakes on a Lincoln Navigator or Ford Expedition and looking for a matched rotor-and-pad package under part number 4502-99172.

Common Rear Brake Issues Addressed

• Rear brake pulsation from worn or uneven rotors
• Brake noise caused by pad wear or inconsistent friction surfaces
• Rust buildup on exposed rotor surfaces
• Longer stopping distances from worn rear brake components
• Uneven pad bed-in after a rear brake service

Installation Notes

Compatible With 2007-2012 Lincoln Navigator, rear; and 2007-2009 Ford Expedition, rear. Before installation, confirm rotor size, caliper condition, and pad fitment against the vehicle’s brake system. The rotors are shipped dry and do not require oil removal before service. Clean the hub mounting surface, inspect brake hardware and calipers for wear, and follow the vehicle manufacturer’s torque and bedding procedures after installation. Part number 4502-99172 should be verified against the vehicle’s rear axle brake configuration before assembly.

Quality Assurance

DFC GEOSPEC rotors are manufactured to OE-style specifications, then inspected for balance and critical dimensions. Each rotor includes a 12-month warranty against defects in material and workmanship. The 5000 Advanced pads are produced with post-cured friction material and premium shims to support consistent braking performance and reduced NVH.
