Product Details
If you're upgrading the braking system on your 1976 or 1977 Ford Bronco, especially if you're aiming for a significant performance improvement to match front big brake kits, this Wilwood Narrow Superlite 4R rear disc kit is a top-tier solution. It replaces the stock 11-inch drum brakes with a modern, high-efficiency disc and drum combination designed for the Big Ford New Style axle. This kit is engineered to provide balanced braking power, ensuring your Bronco stops as well as it goes.
At the heart of this kit are the FNSL4R four-piston calipers, paired with 12.88-inch two-piece rotors. These components work together with the included high-performance BP-10 compound brake pads to offer substantial stopping force. A notable feature is the integrated drum-style parking brake system, which uses an internal shoe mechanism. This design not only keeps the exterior clean for a sleek look but also provides strong holding power when parked. The calipers come in a striking red finish, adding a custom touch to your Bronco's rear end. The 2.38-inch offset and 5 x 5.50 bolt circle ensure proper fitment on the specified axle configuration.
This kit is designed as a comprehensive upgrade, providing the necessary components for a robust rear braking system. While it includes a parking brake function, it's always a good idea to consult the manufacturer's installation guide for specific details on setup and any additional hardware that might be beneficial for your particular build. Wilwood is well-known for its performance brake systems, and this kit represents their commitment to providing advanced solutions for classic vehicles.
