Difference in brake booster rods

I ended up ordering one for a 69 f250 from Autozone. It was one of the only ones we could find with a pic that did not have the adjustable rod. Bolted it in my 68 F100 and it is still working perfectly with no problems. I didn't even have to adjust my brakelight switch. It seems it would have been easier for Ford to make one kind of rod, but something that simple just HAS to be complicated LOL.

Too many different variations of our trucks for them to do that? Disc/drum/F-100/F-250/F-350/2WD/4WD/CS and so on..
Glad you got it on with no issues!
Grandtorinosport, please give us some feedback on the rebuild of your booster. More and more of our parts are becoming obsolete, which will force us to do the same. I had a dear friend way out in the woods in Florida that was retired. He made a living doing just this, (except he was milling parts for all the 20's and 30's cars and trucks-all obsolete parts) for concourse type show vehicles. And like Jamie (Ranchero50) here, my friend was real good at the machine/fab work. It's nice to have sources like that for our dinosaurs!

Will do. Unit was just sent to Karp's yesterday. I expect to see it again in approximately two weeks.

Karp's called last week. Booster is complete and on its way to me. Hope to receive mid week?

what was the cost to rebuild it vs a new ones? i think new ones are about 100.00.

[grantorinosport]

$169.

Since I'm not sure if any of the parts store rebuilds would work (since they are listed for four wheel power drum), I think it's a good deal, all things considered.

From Autozone you can either get one for front drum or front disc, but they are both the same part numbers. Mine works great and was $89.99 plus tax with lifetime warranty.

I just put the complete 68 power disc brake front and HD rear drum system on my 67.
The only modification was the booster pedal rod length. The original power booster had the adjustable rod.
I removed the male end, shortened it about 1/2" and added threads to mount it to the original 67 brake pedal.
The adjustment allows to set pedal height.

Since we are talking about brake pedal rods, is there a difference between manual drum brakes rod and power drum brakes rod? Im converting to DISKS this weekend. Heres what I have.
69 f-100 with manual drum brakes.
I ordered a power drum brake booster for a 69 f-100.---assuming the the rod would still work.
I ordered a power DISK master cylinder for a 79 f-150.--assuming the master cylinder would bolt to the booster.

I looked in the bump wiki and everything. I can't seem to find an answer..I should have grabbed the assembly off the donor truck.

the brake booster has its own rod made into it. the maunal brake rod will not be used when installing the booster. it sounds like you have everything right.

That's funny, because when I look at autozone for a power booster for a 1971 f-250 I only see options for power drum brakes. So I am unsure how you got your great $89 deal.

Is it possible, rather that you were buying a booster for a f-100?

Now perhaps you see why I chose to simply have my existing booster rebuilt, even if it was slightly more expensive.

With all of the other problems I am having, at least I do not have to worry about the power booster not fitting or not working.

[fordman]

as far as disc booster vs drum booster. i think the difference may be that one would have a nonadjustable brake rod vs one with a adjustable rod. but autozone doesnt say that. they say all four booster shown are for drums. which i think is incorrect.

Check for a 1969 F-250. That's what my set-up came off of so that's what I looked up, but put it on a 68 F100. 68-72 boosters should all work the same.

Why are you putting a power "drum" brake booster on when you are putting "disc" brakes on it, and why a 79 F150 if you have a 69 F100. You need to have the matching front disc's, rear drum's, power booster, master cylinder and porportioning valve so the brake system will work correctly.

well i just got done seeing some manual disc brake master differences in another thread. good thing to know. the master should always match the discs prety much as far as bore size in the master. booster vacumm doesnt really change. as far as how they work or dont work. it may take more vacuum to work them or less on some. there are two different boosters single and dual diaprham. there are several booster and how they hook to cetain brackets. but with a 69 booster on his 69 that shoul dbe fine. with a 79 master that should fit on the booste no problem. if his booster has the front adjustign rod then the 79 master should work as it is suppose to and stop the truck. the only question is if the bore size of the master matches his calipers and rear drum brake wheel cylinders. mac'sautoparts.com has a good section in thier paper catalog about brake bore sizes. i have not really gone through it. but it does help match up what you shoul need to put a good braking system together with.

I bought a 68 camper special to be the doner of the power disc brake system for my 67. I swapped the complete front I beams, spindles and calipers. I swapped the whole rear end to get the larger HD drums that match the front disc's, which gave me taller gears but lost my limited slip, but will install an Eaton Elocker to fix that. The porportioning valves were the same, so the valve and rear line stayed. The front line was swapped out with the 68 because they add a "T" block that mounted in an exsiting hole on the 67 and just routed differently through the valve. Every thing bolted right in. Then I swapped the 67 master cylinder for the 68 booster and master cylinder. The ajustable rod had tobe shortend to keep the original brake pedal in the 67 (AWESOME !!)
keep me posted,
