This is a complete bolt in kit designed to work on 1960s and 1970s Ford medium duty F600- and likely similar model- trucks that gives you a modern firewall mounted Super Duty 11" dual diaphragm power brake booster and 1.5" bore master cylinder. This does away with the slave system and under mountd booster. This kit installs in about an hour and requires no cutting or permanent modification. It works with your existing brake pedal. This is meant to work with F600 applications having a factory firewall mounted master cylinder held on by 4 bolts with a 2.5" by 5.0" pattern.


This setup puts out about 1600 psi as well as a large amount of fluid volume and is a great match for medium duty drum brakes. This brake booster is a whopping 11" dual diaphragm. That's about as big as they get. With medium duty applications, valve cover clearance is not an isuse.


Included parts with this kit:

Firewall to SD booster bracket, painted black

Super Duty Brake Booster 1999-2004 style (Motorcraft 5C7Z2005A or equivalent)

Super Duty Master Cylinder (Motorcaft 5C3Z2140MA is 1.375" and 5C3Z2140FA is 1.5" bore)

Custom steel bushing designed to mate SD booster eyelet to factory bake pedal

High quality grade 8 hardware for entire install

Flare adapter fittings- to connect standard 7/16" inverted flare fittings to the master cylinder (common on 1/4" lines)
Flare plugs- for the unnecesssary ports on the MC


These brackets are designed, laser cut, and formed right here in the USA. The parts supplied with them are top quality
