Product Details
This Wilwood rear disc brake kit features a 12.88-inch diameter, two-piece rotor with a drilled surface, designed to work with the Big Ford axle flange and bearing, specifically for a 2.00-inch axle offset. It's built to provide a significant upgrade in braking performance for 1965-1977 Bronco rear axles, complementing front big brake systems. The kit integrates a high-efficiency drum-style parking brake assembly, ensuring both strong static holding power and a clean installation with its neatly hidden internal shoe system.
At the heart of this kit are the FNSL4R four-piston calipers, known for their robust construction and ability to provide balanced braking force. Paired with the two-piece rotors and Wilwood's BP-10 compound brake pads, this setup is engineered to offer optimized stopping power that matches the demands of a performance-oriented vehicle. The two-piece rotor design helps manage heat effectively, contributing to consistent braking performance, especially during spirited driving or when carrying heavier loads. Wilwood offers optional caliper finishes and rotor designs, allowing you to personalize the look and performance to suit your specific build.
This kit is a comprehensive solution for Bronco owners looking to significantly enhance their vehicle's braking capabilities. It includes everything needed to convert your rear axle to a high-performance disc brake system with an integrated parking brake.
