Ensure you can stop your Coyote engine swapped (1964.5-1970) classic Mustang with our compact Hydraulic Brake Assist Unit. Featuring reliable technology to deliver a comfortable, firm, and consistent pedal feel with superior performance. This unit is designed specifically for our classic Mustang Coyote engine swap pedal assembly, which offsets the brake booster and master cylinder outboard to provide clearance for any modular Coyote engine.
Our compact Hydroboost is perfect for any Coyote engine swap as it increases engine bay space, adds hydraulic power-assisted steering capability, improves braking reliability and performance, and allows owners to keep their factory hood hinges.

Kit Includes: 

• 1 x Hydroboost Hydraulic Brake Assist Unit
• 1 x Hydroboost Firewall Mount Plate w/ Hardware
• 3 x Banjo Fitting Assembly
• 1 x Hiem Joint 

NOTE: Factory hood hinge springs cannot be used when the brake assembly is relocated outboard. However, the use of a factory hinge without the springs and studs will work but require a hood prop rod. A low-profile hood hinge can be used as well. 

Make your classic Mustang more practical and experience the comfort of modern driving standards. Upgrade your manual steering and brake vintage Mustang with our premium Hybroboost Hydraulic Brake Assist Unit.

Package this component with our Coyote engine Pedal Assembly and Hydro-boost Brake Master Cylinder for a complete modern driving conversion kit.
