64' Power Brake Conversion
Hey everyone,
Just bought a '64 F100 a month ago. Previous owner installed a power booster, bracket and master cylinder from a '72 F250 2wd.
Right now the brake pedal sits very high compared to the gas and clutch. My guess is that the booster push rod that connects to the pedal is too long. Otherwise the brakes operate very well. Just a high pedal.
Looking under the dash I don't see any way to adjust this pushrod to move the pedal closer to the floor. Then looking on RockAuto I see there's two options for '72 power boosters and one with an adjustable push rod (A-1 CARDONE 5473515) and one without.
Does anyone thing this could be my solve? Also looking at the pic of the booster, does something thread into the opening that would connect to my pedal?
Link to the rockauto part: More Information for A-1 CARDONE 5473515
Thanks in advance!

Ok so I did some more digging and I realized the PO did put in the booster I linked above as it does have the threaded input rod. Problem is it the rod is just too long.
Here's some pics...
Really high pedal:
Input rod/brake pedal:
Booster:
So all that figured out I think I might try to go for a booster like this (assuming it can mate up to the booster bracket i have)
Tuff Stuff 2229NC: 9" Brake Booster Dual Diaphragm | JEGS
Then I can put on one of these to get the right pedal height
Tuff Stuff 4750: Pedal Rod Extension Kit 4pc Includes: | JEGS
I've never replaced a booster before but it seems rather straight forward. Any advice?
Thanks!

It's possible all you actually need is the brake pedal from a 1972 truck. I'm not positive about that but my 65 truck has a 1979 booster and the 79 pedal and it is about where it should be.

Mind getting me a sideview pic of your pedal like mine above?
I see one on ebay right now for $50....hard to tell if the curve is better or what about the design would make it sit better.

Brake pedal
This pedal is marked with engineering # D7TA-MA, PWR it is for an auto trans. You will likely need one for a standard trans. I suggest contacting this guy and see if he has what you need Flashback F100's - Home
He has taken a bunch of trucks apart and knows a lot about what fits what.

1973/79 F100/350:
There are TWENTY TWO different brake pedals, NINETEEN different P/B boosters, SEVENTEEN different master cylinders, SEVEN different clutch pedals, I kid you not!
Whatever booster is used must match the brake pedal.
--------------------------------------------------------------
1968/72 F100/350:
There is ONE brake pedal, ONE clutch pedal, with/without P/B makes no difference.

Crop Duster: thanks for the link I will check out the site. Though it seems to be down right now.
NumberDummy: are you saying it's as simple as getting a '72 pedal to match my '72 F250 Booster/Master?

AFAIK, it will not work. 1964's use different master cylinders and related parts than 1965 and later.

As far as the '72 pedal in my '64 - as I mentioned I have a master cylinder and master combo from a '72 in my '64. The only stock '64 part left in the brake linkage is the pedal.

IMHO, just cut the brake pedal rod shorter.
Set the pedal where you want it, measure that distance to the inside of the booster contact point to connection on the pedal.
Match the profile on the end of the rod and call it a day.
Just my 2 cents

SixtyFour -
Just to let you know: Your truck is not a '64. Its either a '65 or '66.
It may have been built in the 1964 calendar year but it's definitely a later model.
The inner fenders and steering column mount give it away.
Cheers

Either way I'd have to take the current booster off and just replacing it doesn't take a bunch of fab work.

The only way to verify the year is by the last 6 digits of the VIN
Truck has a 1965 grille, 1965/66 upper grille panel and suspended accelerator pedal.
Suspended accelerator pedal: 1965 F100/250 2WD from serial number 696,001; 1966 F100/250 2WD & 1966 F100 240/300 4WD
The front fender emblem was used on the sides of the hood in 1963/64. Only early 1965's used it as a front fender emblem.
The crossed flags front fender emblem is from a 1962/64 Galaxie.
The hood front emblem: 1961/64 all, 1965/66 I-6 only.

This truck isn't close to being original, as it's a Frankenstein Monster with parts swapped from gawd only knows what.

I'll look at the VIN later - but I could have sworn when i looked it up when i bought it it was was '64.
