MOAB Upgrade For Vacuum Boost Power Brake System SKU: 2983NET

MOAB Upgrade for Vacuum Boost Power Brakes | 66–77 Ford Bronco

Take your Bronco’s braking performance to the next level with the MOAB Vacuum Boost Upgrade Kit—a premium solution for converting most aftermarket power brake systems to the legendary WILD HORSES MOAB setup. Built around precision components and engineered for clean, reliable installation, this kit delivers enhanced brake feel, tunable balance, and rugged durability worthy of any Bronco build.

At the heart of the system is a Wilwood aluminum master cylinder, paired with our adjustable MOAB proportioning valve. You’ll have full control of front/rear brake bias thanks to the easy-to-reach adjustment knob. Stainless steel hard lines connect the master and valve, while braided stainless flexible hoses route to the factory brake lines at the frame via a dedicated frame-mounted bracket.

This kit is engineered for direct fitment on 1967–75 Bronco factory lines without adapters. 1976–77 Broncos require minor line modifications, and the additional lines are included when you select that year range at time of order.
