Rear Brake Kit for Ford and Lincoln

The Dynamite Friction DFC GEOSPEC Coated Rotors with 5000 Advanced Brake Pads - Ceramic and Hardware kit is a rear disc brake service kit built for OE-style fitment and consistent braking performance. Part number 4512-99243 is engineered for rear brake service on select Ford Expedition, Lincoln Navigator, and Ford F-150 applications.

Key Features

• Rear disc brake kit with coated rotors, 5000 Advanced ceramic pads, and hardware
• GEOSPEC coated rotors help resist rust and arrive dry for installation
• Non-directional rotor finish supports even pad bed-in and smoother stops
• 5000 Advanced pads are post-cured and scorched for stable friction performance
• Premium rubber-steel-rubber shims help reduce noise, vibration, and harshness
• Hardware uses PTFE coating, vulcanized rubber, and stainless steel construction
• Part number 4512-99243 for rear brake service applications

Product Details

DFC GEOSPEC coated rotors are cast to G3000/G11H18 specifications and machined to tight tolerances for durability and OE-style stability. The silver-gray coating is designed to resist corrosion better than conventional paint or zinc finishes, and the dry-to-install design eliminates rotor cleaning before assembly. The 5000 Advanced ceramic pads are formulated for specific axle applications, then post-cured and scorched to reduce initial break-in time. This rear brake kit is a practical choice for drivers servicing a 2018-2021 Ford Expedition rear brake system, a 2018-2021 Lincoln Navigator rear brake system, or a 2018-2020 Ford F-150 rear brake system with electric parking brake and excluding police vehicle use.

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

Vehicle Fitment

• Fits 2018-2021 Ford Expedition, rear.
• Fits 2018-2021 Lincoln Navigator, rear.
• Fits 2018-2020 Ford F-150, rear; electric parking brake; excluding police vehicle.

Common Brake Service Issues

• Rear brake noise from worn hardware or fatigued clips
• Uneven pad wear caused by corroded or stressed brake hardware
• Brake pulsation from worn or out-of-spec rear rotors
• Longer stopping distances from aged rear pads and rotors
• Rust buildup on exposed rotor surfaces

Installation Notes and Tips

Confirm rear axle fitment before ordering, especially on 2018-2020 Ford F-150 models with electric parking brake and police vehicle exclusions. Inspect caliper slides, pad contact points, and hub surfaces during service so the new rotors seat correctly. The non-directional rotor finish is intended to support faster pad bed-in and quieter operation after installation.

Quality Assurance

DFC rotors are 100% inspected for critical dimensions and balance, with vented rotors electronically mill-balanced when required. Each rotor is backed by 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 characteristics and improved NVH control.
