'67-only power brake setups [LARGE PICS]

[jbrown414]

That information would of been great to have yesterday... Just pulled a master cylinder/booster and pedal assembly from a 79 today. Guess I will try and sell them seeing how they won't fit in my 67.


Well, let me ask some questions. Will the brake booster brackets that I now have from the 79 work if I just order a brake booster and master cylinder for a 68-72 from a parts house? Also, I have seen on some online catalogs and I think someone mentioned it earlier, that some boosters, like the one from NPD, come with an adjustable pushrod. If one was bought for a 68-72, could it be adjusted to fit a 67 pedal?

Well everyone, I've been working for almost 6 hours putting together this new photo tutorial...and I think it turned out pretty good. There's a ton of pictures on there...definitely check it out. I guarantee that you'll be learning a thing or two! I know I did!

Comparing Clutch/Brake Pedals & Brackets

I also added the '67-only information to this page, just so we could have it all together in once place on the site, and so that visitors wouldn't have to search the forums to find this thread in the future.

...Well, let me ask some questions. Will the brake booster brackets that I now have from the 79 work if I just order a brake booster and master cylinder for a 68-72 from a parts house?...

First of all, does the booster assembly from the '79 look like this, with the curved pushrod and angled brackets?



If so, I'm not sure, but I highly doubt it. If you read the webpage I just posted above and check out the pics, I think you'll understand how that curved rod and the angled booster mounting brackets are probably not going to work with a '68-'77 booster. But I didn't have a '78-'79 booster to actually attempt mounting, so I can't say for certain it won't work. I'd sure love for you to try though, and then send some updates with pictures to let us know for sure how it turned out.

No. The adjustable pushrod isn't going to allow that much adjustment. It's only good for maybe 1/2", not the 1-1/8" (roughly) that you'd need. Here's a picture of the adjustable pushrod, just for the visual:



However, it might be possible for you to trim and rethread the end of the pushrod, to shorten it up enough to work...but to be honest with you, I wouldn't hold your breath. Sorry I couldn't have gotten this info to you a day earlier to save you the time and money, but I think you'd be better off cutting your losses now on the '79 setup, and find the pedal pivot bracket from a '68-'72 and then use any '68-'77 power booster and brackets.

Don't sweat it Keith, pulling the parts from the 79 weren't that difficult and didn't break the bank. Now, if I had attempted to put them, that might have been a different story.

The booster backet and pushrod look like the ones you posted. I won't be going to another yard till this weekend. I'll try and get everything I need from a 68-72 and try to do some comparisons. As always, thanks for the info.

The booster doesn't have to necessarily be from a '67-'72...the booster setups are basically the same up through '77 and will bolt right up. But the older versions are IMO better anyway, since they're a fatter dual-diaphram unit.

[jbrown414]

This stuff is so confusing... really glad we have this site. Let me see if I can get this straight. My 79 boster/master cylinder/pedal bracket are out.

1. I need to get a booster/brackets/pushrod from a 68-77, preferably 68-72 due to the dual diaphram.

2. Then I need to get the pedal bracket and pedal from a 68-72.

Does this sound right?

[Wes]

Yes J Brown, for ease of install the pedals and pivot bracket should be 68/72
and you are correct for booster/brackets/pedal rod.

will the pedal bracket from my 77-78 work?(hopefully)

Or: did I ask this question already........

[FORDification]

...1. '73-'79 pedal pivot brackets will NOT bolt up into a '67-'72 truck without major dash modifications...

No, it won't fit the bumpside dash.

I figured you'd say that, I hate Mondays......

The adjustable push rod I got from Master Power Brake probably has two inches of adjustment in it and if you cut some of the threads off you get even more.But there wasn't enough adjustment in the rod they send in the kit I had to call back and get more adjustable parts, now all is well.

so your saying your not sure the first pick of the booster pushrod and brackets may or may not be the same as the 78-79 oddballs?

i found a 79 F350 dually (same dual piston calipers i have on my 79 F350 single wheel front and rearend for the swap) in the local boneyard and it had the dual diaphram booster (even if i have to use it as a core on a reman it looks good to use for now...) and holes in the brackets holding the booster to the firewall
maybe i was crazy...

so a guy like me (built a twin engine olds with Al) would have the ability to make the 79 pedal fit the 68 pedal bracket in my 4spd CS you mentioned grinding so i'm sure i can hack it (pun thouroughly intended )

if the 77 250 is still there should i grab the firewall mounting brackets for the booster from it and throw the 79 booster on the 77 bracket or am i deffinatly looking at getting a reman for a dual diaphram booster for my 68 and just throw the 79 booster as the core?

I'm interested in your pics, if it's nothing big i can weld and machine the pedal to work with the 79 booster and (67-77 right?) firewall brackets and my 68 manual drum pedal

these parts are the last bits i need to finally get off my butt and get some work done on the 79 dual piston disk brakes on my baby...i've been fixing Al's junk to much lately

I'm not sure which picture you're referring to. The one above with the curved pushrod is the '78-'79 version, which requires the '78-'79 pivot bracket and pedal.

You want my honest opinion?

Too many people try to re-invent the wheel, in my opinion. Just because you have a '79 booster doesn't mean you HAVE to use it. Yes, it would be nice...but the work involved to do so is not worth the all the extra effort required, especially when there are zillions of trucks out there with the parts you need to just bolt up a great functioning system.

You've already got the correct underdash bracket and pedal in your '68. Instead of all the work in reverse-engineering the '79 pivot support bracket and pedal, why not just find any '68-'77 booster and bolt it up? You'd be done in less than 30 minutes, with no hacking involved. Heck, if you're going to buy a replacement booster anyway, then all you really need are the mounting brackets.

What I DON'T know right now is if someone could use the '77-older brackets and pushrod on a '78-'79 booster. I don't even know if the pushrod could be replaced...I've never looked at that closely.

Just find the parts you know will bolt up and be done with it.

[spartman]

Does this info apply to the factory hydroboost that ford had?

[turbocharged400sbc]

I'm not sure which picture you're referring to. The one above with the curved pushrod is the '78-'79 version, which requires the '78-'79 pivot bracket and pedal.

i could swear the dual diaphram booster on the 79 F350 flatbed dually had holes in the sides of the mounting brackets unlike the first photo with the single diaphram (jbrown414 can you tell us if that was a 150/250/350?) the bolt spacing on the 79 booster are identical to the ones on the bracket acording to my tape measure

You want my honest opinion?

always keith...

not zillions around here... i just havent found any dd boosters around here...this 350 is it and at least it can be a core...but if the brackets are the same as the 77 that was in the yard as well i dont think i'll swap them but it might be worth it...the other thing is the master was fairly new and the truck has the same type brakes as the 79 F350 single suspension/brakes donor i have all my parts from

i guess i need to find out what a reman would go for and see if it's core charge is worth getting the Jyard unit for a few bucks back...

i was just wondering if the 79 pedal and booster work is something that i can do...i have the tools but like you said bolt in is better...it's just hard to find parts around here

What I DON'T know right now is if someone could use the '77-older brackets and pushrod on a '78-'79 booster. I don't even know if the pushrod could be replaced...I've never looked at that closely.

if it warms up a bit and i can get over to the Jyard i may just try that out if i'm wrong about the booster brackets on that 79 350 dually

Just find the parts you know will bolt up and be done with it.

i dont ever seem to go with the easy way of doing things...

spartman: - None of the above information has anything to do with Hydroboost setups. Those are a completely different part altogether, and AFAIK there are no bolt-in Hydroboosts for our trucks...they'll all require some fabrication.

turbocharged400sbc: - The info I presented isn't by any means complete, it's just everything I know up to this point. It's possible that '78-'79 F350s got the earlier setup. As mentioned, it's also possible that the '78-'79 booster units will accept the earlier brackets and pushrods, and if so that would mean it would be a direct bolt-on after the parts were switched around...but I'm just guessing here, since I haven't investigated that yet.

If for whatever reason you find they won't work, then maybe you could try using the '79 unit as a core for a '77-older style...I doubt the counterman would have both of them out of the box sitting side-by-side so that he'd notice the difference in the pushrod. But then you'd still have to find the correct brackets...if the existing pieces won't work. I wish I had a '78-'79 booster here so that I could do some comparisons. All I can say at this point is to give it a try, if you're adventurous, and let us know what you find out.
