booster bracket

[jimmy828]

getting ready to install a brake booster on my 1969 f100 which as of now it has manual brakes. I am having trouble locating a new or used bracket for the booster.is there any interchangeable parts?I will appreciate any tips on this project!

67-77 1/2 booster brackets will work. there are some different types of booster brackets that started to be used in the 77 1/2 -79 trucks. they don't work correctly for our application.

Starting in 73 (or thereabouts), some of the trucks used a cantilever bracket with a trapeze linkage. Those units will work, but you may have to make some modifications to make the brake light switch work properly.

what mods? the brake light switch is on the brake pedal. with the flat bar type you just drill out the flat bar to reach correctly with the brake pedal.

Depending upon the year of the booster, the rod (actually a flat bar) may be too short to allow the pedal to come to the top like it should.

The way I corrected mine was to make a new "stop" for the switch by taking a piece of 1/8 x 3/4 flat stock, bending it, and bolting it to the steering column support. Here's a picture of what I did to correct mine:

Another way would be to make a longer rod/bar that would give the pedal back all of it's travel.

I've had a lot of heated discussions with folks who said that wasn't necessary. I've also had a lot of less-heated discussions with folks who ran into the same problem I had.

In 73 or 74 (can't remember which right now), Ford lowered the brake pedal on power brake trucks so that the location was like other manufacturers. I don't know if this shorter "rod" was how they did it or not, but the '75 booster I put on mine had the shorter rod and the pedal is pretty close to what I would consider "normal" for a vehicle with power brakes.

I can also vouch for the fact that mine is not a "one-time-only" thing. I've had several other used booster setups that were exactly the same, and I've got an NOS Power Brake Kit for a 76 that has exactly the same length rod. It also has a new brake pedal, which I've compared to one from a 70 model, and there's not a lot of difference, at least not enough to compensate for the shorter rod. Here's a picture of the contents of the kit:
