I have been putting together a list of brake booster part numbers to better understand all the types and interchangeability. I am working with a manufacturing company to create these boosters brand new once again. It seems that these are not available anywhere- the only thing I can find for a lot of them online is a return and rebuild service.

There are 12 boosters on this list and I am guessing that just about every model of ford truck can be served without actually recreating all 12. There is hopefully some interchangability. It costs a few thousand dollars per each part number to begin manufacturing.

I am hypothesizing the following things- if you have knowledge one way or the other on this list, please chime in:

1. Generally, there were boosters with three main types of rods/clevis (the part that connects to the pedal) - a long straight one, a short straight one, and a tear drop shaped bent one.

2. The teardrop shaped bent rod I understand to almost exclusively come in a longer form on F series trucks. There is a shorter version teardrop style rod but it was mostly on e series vans.

3. Of these three styles of boosters, there is a single or dual diaphragm version. the two diaphragm types are interchangeable on a truck that would have come with either type (where there is sufficient physical room)

4. Master cylinders will interchange between nearly all of the brake boosters- at least mount up, not necessarily be correct for the type of drums/discs, etc.

5. the 1976- 1977 bronco brake booster is not interchangeable with any of the F series boosters.

6. I think 6 versions of boosters could serve nearly all F series dentside trucks- a single/dual diaphragm for each of the three types mentioned above.

7. with the exception of D7TZ2005A, there are not online sources for purchasing these boosters outright, without a core.

Any input would be greatly appreciated, these trucks deserve to have good brakes available to decent prices!

 

Good luck with this!

 

Hope you can do it , good luck as I know many have had issues finding some replacements

 

The dual diaphragm is the most desirable and can service the majority of these trucks. If you were to get one made that would be my first choice. They are preferred for better braking and for high rise valve covers.

 

To much thinking going on. 2nd Gashog on the universal dual diaphragm, providing you have enough vacuum. If not Hydro-Boost is the way to go.

 

ok I'm working on getting exact dimensions on these to confirm their interchangeability. having less inventory would certainly be nice

 

These work.

but those are GM parts haha

 

They work HAHA. Do you only use Ford bolts and the such.

 

not at all! But all jokes aside, that is a booster meant for a car and a wimpy 1" master cylinder. That would be a down grade from most factory ford systems.

 

Not disagreeing with you, but all of my 1/2 ton dentsides have a 1" bore master. I guess those GM ones would be more of a side-grade than and up or downgrade.

Do the 3/4 and 1-tons have larger bores?

 

According to a search on rockauto, it looks like 1974 F250s could have come with either a 1" bore or a 1.25" bore master. interesting!

 

I've been running it for 5yrs, it will still throw you into the dash. I do have a 79 suspension in a 66 F250 and drive 5-10K mi a year. Can't imagine it being better.

 

I sure hope you have success with this venture!
I am trying to get a new booster for my truck right now...... LUCKILY..... I have found the one that seems to be a replacement for the one that came out of my truck.
All I have to go by is the shape, the length and look of the rod. (It is the 4" short straight rod).





Mine seems to match the Cardone #54-73703 you list on your chart above. Your chart has now given me a boost of confidence! THANKS!!

 

I agree with gashog, i would like to have a dual diaphragm booster for my 77 F-150 4X4. Please keep us informed of the progress on these! And Thanks!! -Ed
