Product Details
This Wilwood kit gives you a complete rear disc brake upgrade for your Bronco, specifically designed for Small Ford rear axles with a 2.36-inch offset and 5 x 5.50 bolt circle. It replaces your stock 10-inch drum brakes and offers a significant improvement in stopping power and parking brake function. You'll receive a pair of red Forged Narrow Superlite 4R (FNSL4R) four-piston calipers, two-piece 12.88-inch rotors, and high-performance BP-10 compound brake pads. This kit also features a drum-style parking brake assembly with an internal shoe system for a clean look and solid holding power.
The FNSL4R calipers are forged for strength and feature a narrow design that fits well with the 2.36-inch offset. The two-piece rotor construction helps manage heat and allows for easier replacement of the rotor ring if needed. The BP-10 pads are a popular choice for a good balance of street performance and stopping power, complementing the front big brake kits often used on Bronco platforms. This setup is designed to provide optimized and balanced braking, especially when paired with front upgrades.
When installing this kit, you'll want to ensure you have the correct tools and refer to Wilwood's installation instructions, as it involves replacing the entire rear braking system. The integrated parking brake system is a notable feature, offering a cleaner appearance than external drum-in-hat style parking brakes. This is a substantial upgrade for anyone looking to enhance the braking performance and aesthetics of their classic Bronco.
