Pulled off the drums to investigate a sticking wheel cylinder and noticed the entire cable self adjusting assembly is gone. Is deleting this a common practice, assuming one doesn't mind doing the occasional adjustment? Is the lower spring setup acceptable as is? It looks like this spring would have originally hooked to the self adjusting cable arm.
In short, in the late 80's many just didn't know or care about the self adjusters and removed them when they failed to operate properly instead of fixing it....and they are very simple to fix and operate very effectively....a big mistake to remove IMHO. and no, the lower spring does not connect at that location...there is an arm that essentially acts as a lever to actuate the adjuster...and the (one) end of the adjuster attaches to a spring of similar size and type. Unfortunitely, its just kinda jerry-rigged.
The parts are still available but if you can't locate them in SC, these guys are basically a salvage yard just for brake parts....
Ok thanks for the info. I see there is a self adjuster repair kit available from Napa that looks to include all parts of the cable and guide. According to the Ford diagram for 67-72 4x2 F100s, I'm also missing another spring? A long one that runs horizontally? I have the Raybestos complete brake hardware kit and this spring is nowhere in it.
In addition, that wheel cylinder looks a little damp.
Yeah that's why I was in there to replace that wheel cylinder. Anyone know about the spring shown in the parts diagram above? My spring kit didn't include it and there is nothing like it currently installed.

It's called the brake assist return spring.....they were used on both the trucks and cars.....have to buy separately.....

How come the kits don't have these? In the shop manual for my '64 it's shown in the pic for the front axle though is not named or identified unlike every other spring or component. Everybody leaves them out since they aren't in the kits, but one thing about Ford (and everybody else) if a part wasn't necessary, they probably wouldn't have included it in the first place. Now my OCD is kicking in.
Also called retraction assist or retracting spring aka "antirattle" spring. Generally claimed on various automotive forums as not needed. Supposedly, they help to prevent glazing of brake linings or reduce squeeks or somesuch. It's interesting to read old forum posts from Mustang forums and trucks, everybody has the same question and wants to know what's up with that spring. Seems like since it isn't needed, there ought to be a pile of 'em somewhere.

Well, here's the skinny...….
Back in the late 1970's when the aftermarket was really starting to push the disc conversion kits (which were pretty crappy), the industry got the brake spring mfg's to state that the brake assist return springs were not necessary and they deleted them from the kits....in not all, but most saw the brakes hanging up (and by the mid 80's they stopped mfg them for the passenger cars) which then the response was "drum brakes are no good or now you know why Detroit uses disc brakes)…….
for years on my toy I cut the ones for the F100 down to fit my stang but recently I fabbed up an assembly myself that works excellent and I can simply adapt the F100 spring with no welding required.
Now I'm confused (not a difficult task) though still. That particular part # is 4WD? Or, the retracting assist springs were only used on 4WD? The latter doesn't make sense. They were used on all kinds of passenger cars, near as I can tell. It's always interesting to hear people exclaim how a certain part is "not needed". Maybe, but if it's all the same, I'd like to try them. The 64 shop manual plainly shows the long spring, Hm.
I spent a while on that famous auction site with a couple different part #s and search phrases trying to find a pair. It's personal now!! haha.
