Product Details
Starting with the 12.88-inch, two-piece rotors, this Wilwood Narrow Superlite 4R rear disc brake kit is built to offer a significant upgrade for your 1965-1977 Bronco's braking system. Specifically designed for Big Ford rear axles with a 2.00-inch offset and a 5 x 5.50 bolt circle, this kit aims to provide balanced braking performance that complements front big brake setups. The kit includes the FNSL4R four-piston calipers, which are known for their efficiency and ability to work well with the included high-performance BP-10 compound brake pads.
Beyond the primary braking components, this kit also incorporates a drum-style parking brake assembly. This internal shoe system is neatly hidden, offering a clean look while providing strong static holding power when parked. This integrated approach means you get both improved stopping power and a functional parking brake without adding extra bulk or complexity to the rear axle assembly. Wilwood offers optional caliper finishes and rotor designs, allowing you to tailor the appearance and performance to match your specific build and style preferences.
When installing this kit, it's important to note that it's designed for specific rear axle configurations. Ensure your Bronco's rear axle is a Big Ford type with the correct 2.00-inch offset and the 5 x 5.50 bolt pattern. Because this is a significant brake upgrade, it's always recommended to consult the manufacturer's installation instructions for proper setup and to ensure optimal performance and safety. This kit is a comprehensive solution for Bronco owners looking to enhance their vehicle's braking capabilities significantly.
