Product Details
This Wilwood rear disc brake kit gives you everything you need to upgrade the braking system on your 1965-1977 Ford Bronco with a Big Ford rear axle, 2.00-inch axle offset, and 5 x 5.50 bolt circle. What you get in this kit is a complete rear brake setup featuring FNSL4R four-piston calipers, 12.88-inch SRP drilled two-piece rotors, and a high-efficiency drum-style parking brake assembly with internal shoes. This is Wilwood's solution for Bronco owners looking to significantly improve their vehicle's stopping power, especially when complementing a front big brake upgrade.
The FNSL4R calipers are known for their robust construction and effective clamping force, working in tandem with the BP-10 compound brake pads to deliver balanced braking performance. The 12.88-inch SRP rotors are drilled to help dissipate heat and reduce weight, contributing to consistent stopping power even under demanding use. The integrated drum-style parking brake system is neatly hidden, providing strong static holding power for parking while maintaining a clean look. This kit is designed to fit directly onto Big Ford rear axles with the specified 2.00-inch offset and 5 x 5.50 bolt pattern, making it a straightforward upgrade for many classic Bronco builds.
When installing this kit, remember that it's designed to work with your existing Big Ford rear axle flange and bearing. The internal shoe system for the parking brake offers superior holding power compared to many stock setups. Wilwood offers optional caliper finishes and rotor designs if you want to further personalize the look of your build, but this specific kit comes with red calipers and drilled rotors.
