1967–1970 Ford Mustang Electric High Power Master Kit Product Description Shop 1967–1970 Ford Mustang Electric High Power Master Kit for a modern brake-assist upgrade on classic Mustang builds. Replacing a used Mustang power brake setup can help improve pedal assist, reduce dependence on engine vacuum, and modernize an aging braking system. Order Ford Mustang electric high power master kit when upgrading a restoration, restomod, or performance car that needs strong and consistent brake assist. Designed for compatible 1967–1970 Ford Mustang applications, this kit combines an electric-powered brake assist solution with master-cylinder hardware for a compact, performance-focused setup. It is especially useful on engines with low manifold vacuum, aggressive camshafts, forced induction, or limited room for a traditional vacuum booster. Key Features Fits compatible 1967–1970 Ford Mustang applications Electric power brake assist configuration Helps reduce dependence on engine vacuum Suitable for low-vacuum performance engines Designed for restoration, restomod, and performance builds Can provide consistent brake assist regardless of engine vacuum level Compact alternative to some traditional vacuum booster setups Useful with aggressive camshaft or forced-induction combinations Master-cylinder-based braking upgrade Helps modernize classic Mustang brake performance Product Specifications Specification Details Product Type Electric High Power Master Kit Vehicle Ford Mustang Model Years 1967–1970 Position Brake Master Cylinder / Firewall Brake Assist Electric Master Cylinder Verify Kit Contents Reservoir Verify Electrical Pump / Assist Unit Verify Pressure Switch / Controller Verify Mounting Brackets Verify Brake Line Adapters Verify Power Requirement Verify Application Restoration / Restomod / Performance Upgrade Why Choose Electric Brake Assist? Traditional vacuum boosters rely on adequate engine vacuum. Performance engines with large camshafts, forced induction, or modified intake systems may not provide enough vacuum for consistent assist. An electric high-power system can provide a more dependable source of brake assist while keeping the engine bay cleaner and more flexible for custom builds.

Intended for compatible 1967–1970 Ford Mustang applications. Verify exact firewall and pedal configuration. Confirm whether the car currently uses manual or power brakes. Check pedal ratio and pushrod geometry. Verify master-cylinder bore size against the complete brake setup. Confirm compatibility with front disc / rear drum, 4-wheel disc, or other brake configurations. Check engine-bay clearance around valve covers, shock towers, headers, and wiring. Verify electrical-system capacity before installation. High-current electric assist systems may require upgraded wiring, fuse, relay, battery, or charging-system support. Confirm brake-line fitting sizes and routing. Verify whether a proportioning valve is required or included. Modified firewalls or aftermarket pedal boxes may affect fitment. Professional bleeding and complete brake-system inspection are recommended after installation.

Asked about this part

What is this product?
It is an electric high-power brake master / brake assist kit for compatible 1967–1970 Ford Mustang applications.
What years does it fit?
It is intended for 1967, 1968, 1969, and 1970 Ford Mustang models, subject to the correct firewall, pedal, and brake configuration.
What does “Electric High Power Master” mean?
It refers to a brake master and assist system that uses electric power rather than relying only on engine vacuum.
Is this a vacuum booster?
No. The system uses electric assist.
Why use electric brake assist?
It can provide more consistent assist on engines that produce low or unstable manifold vacuum.
Can it work on a stock engine?
Yes, if the system is correctly matched and installed.
Does the engine need manifold vacuum for this system to work?
The electric assist system is designed to reduce or eliminate dependence on engine vacuum.
Is this a complete brake conversion kit?
It is focused on the master-cylinder and electric-assist portion of the system. Exact contents should be verified.
Does it include a master cylinder?
It typically does, but verify the exact package contents.
Is the system for manual brakes or power brakes?
It can be used as a power-assist upgrade, but the starting pedal and firewall configuration should be verified.
Can it convert a manual-brake Mustang to power assist?
Yes, if the kit is designed for that application and the correct pedal geometry is used.
Can it replace a vacuum booster?
Yes, in compatible applications.
Can it replace a hydroboost system?
Potentially, but the hydraulic and pedal configuration must be checked.
Why does pedal ratio matter?
It affects pedal leverage, travel, and the force applied to the master cylinder.
Can it work with 4-wheel drum brakes?
Possibly, but the system configuration and hydraulic requirements should be verified.
Can it work with aftermarket big brake kits?
Yes, if master-cylinder bore and hydraulic volume are appropriate.
Can it work with Wilwood brakes?
Possibly, if properly matched.
Can it work with Baer or other aftermarket brake kits?
Possibly, depending on the hydraulic requirements.
What should I verify before ordering?
Confirm the 1967–1970 Ford Mustang model year, firewall and pedal configuration, manual or power brake starting point, transmission and clutch linkage, pedal ratio, master-cylinder bore, front and rear brake configuration, proportioning requirements, available engine-bay clearance, electrical-system capacity, brake-line fittings, and exact kit contents before purchase.
