Product Details
This Wilwood EPB/FNSL Rear Kit includes everything you need to significantly upgrade your vehicle's rear braking performance. You get a pair of 12.88-inch diameter SRP series two-piece rotors, designed for robust heat dissipation. It also includes Wilwood's FNSL four-piston calipers, which are built for strong stopping power and feature an integrated electronic parking brake (EPB) system. The kit also contains all the necessary mounting brackets, hardware, and brake lines to complete the installation, making it a comprehensive solution for a rear brake overhaul.
The SRP series rotors are a standout feature, constructed from a high-carbon iron alloy and featuring a unique slotting pattern. These slots help to sweep away gas and dust that can build up during hard braking, ensuring consistent performance and a cleaner rotor surface. The FNSL calipers are a well-known choice for their solid construction and reliable performance, offering a substantial improvement over stock braking systems. The integrated electronic parking brake is a modern convenience that simplifies the system by eliminating traditional cable-actuated parking brake mechanisms, often controlled via a dash-mounted switch.
This kit is designed for vehicles utilizing the Big Ford rear axle, a common setup in many trucks and muscle cars. The 2.50-inch offset is specific to certain axle configurations, so it's important to confirm this matches your vehicle's rear end. Upgrading to a big brake kit like this one is a significant step for any vehicle that sees spirited driving or heavy use, as it dramatically improves stopping power, heat management, and driver confidence. Ensure you consult the manufacturer's installation guide for specific details regarding your vehicle's axle and the EPB system integration.
