This is a pair of brake booster brackets, machined bushing, and hardware to install a 99-04 Super Duty hydrobooster into a 1973-1979 Ford F150 / F250 / F350. This listing DOES NOT include the brake booster, master cylinder or plumbing. You will need to purchase separate.
 
This is a first of its kind- a bolt in kit designed to work on 1979 and older Ford F100, F150, F250 and F350 trucks that gives you a later model Super Duty hydroboost  brake booster and master cylinder! You will get significantly more fluid pressure and volume coming out of this master cylinder. This kit installs in about an hour and requires no cutting or permanent modification. It works with your existing brake pedal.
 
The master cylinder will have a 1 3/8" (1.375") bore. Your factory master cylinder likely has a bore of 1.00" or 1.25". Assuming you have the larger 1.25" bore, the factory bore size has surface area of 1.227 square inches. A bore of 1 3/8" has surface area of 1.485 square inches. This makes for an increase of about 21% of fluid coming out of the master cylinder as compared to your factory one, with the same amount of brake pedal movement. In other words, goodbye squishy/low brake pedal! This is overkill and maybe too much for drum/drum brakes. this is really meant for disc brakes! 
 
This brake booster will be powered by hydraulic fluid from the steering pump. These boosters are about as powerful as they get! Most factory 73-39 brake boosters are either a single 9", a single 11" or a dual 9". You will feel like your braking power doubles with this kit. This is really meant for disc brakes. Drum brakes will feel like they want to lurch and lock up.
 
Original booster types: 
Long striaght rod booster- common for most 1976 and older. Note that 1967 had a unique length
Cantilever booster- common for 1977 and 1978. Easily identifiable by looking under the dash and seeing a flat bar connecting to the brake pedal
1979 angled style- common for 1979, the booster sits up and at an angle, with an offset eyelet on the rod connecting to the pedal.

Included parts:
Firewall to SD hydroboost booster bracket
Custom machined steel bushing designed to mate SD booster eyelet to factory bake pedal
High quality grade 8 hardware for entire install
 
 
Not included parts that you need to buy:
Super Duty Brake Booster 1999-2004 style (Motorcraft BRB33 or similar)
Super Duty Master Cylinder w/ reservoir, 1999-2004 style (Motorcaft 5C3Z2140MA or Oreilly NMC23201 or similar) 
Brake lines (two 36" lengths will plumb in the master to the factory proportioning valve)
Plumbing (the two fittings in the booster require M16-1.5 o-ring and M18-1.5 o ring fittings)
 
 
Optional extras:
I sell the two flare fitting adapters that go into the SD master and have 3/8" female inverted flare fittings. This is the fitting size that common 3/16" brake line nuts have.
 
Pliumbing- I also sell the power steering side high pressure plumbing for these kits. This requires that you tell me the stering pump fitting type and steering gear fitting type, so please message before or after purchasing. I use high qualuty 6an PTFE hoses that have a nice stainless finish. I also use premium steel (not aluminum) hose ends, high quality adapters, etc.
