Dynamic Friction Company Disc Brake Kit P/N:4512-54251

Service the rear brakes on your truck in one order with the DYNAMIC FRICTION brake kit 4512-54251. It is a direct-fit rear kit for the 2021-2026 Ford F-150 (engine: All). It pairs DFC GeoSpec coated rotors with DFC 5000 Advanced brake pads and a DFC hardware kit, so the main rear brake components arrive together in one package.

• GeoSpec coated rotors: Cast to the G3000/G11H18 cast iron specification and designed to meet the same form, fit, and function as OEM brake rotors. A silver-gray painted finish is designed to resist rust better than conventional paint or zinc coatings. The rotors are processed and shipped dry, so they need no pre-degreasing, and the pads sweep the coating away in use.
• Precision machining: Each rotor is precision cut and mill-balanced, with a non-directional finish that promotes faster pad bed-in and smoother stops. Every rotor passes a 100% inspection of its critical attributes.
• 5000 Advanced pads: The asbestos-free friction is formulated for the specific axle and 100% post-cured for stable friction performance. The pads are scorched to remove uncured bonding agents, which minimizes the initial break-in period. Rubber-steel-rubber shims help reduce noise, vibration, and harshness.
• Hardware kit: Combines PTFE coating, vulcanized rubber, and stainless steel, with rubber-coated abutment clips. It is designed to help reduce noise, vibration, and premature wear.

Brake hardware is often overlooked during a brake job. DFC notes it can become stressed, fatigued, or corroded within 1-2 years, which reduces spring tension and allows excess caliper movement, uneven wear, and noise. This disc brake kit lets you replace the rotors, pads, and hardware at the same time. Grinding, squealing, pedal pulsation, or longer stopping distances are signs the rear brakes may need service. No modifications are required, and the quantity per application is 1. Each rotor carries a 12-month warranty against defects in material and workmanship.
