Brian I too agree as some of the guys have pointed out, your drums are out of spec. With fresh shoes your adjuster should look like the image you found on the internet. I suspect that you didn't have the drums turned. With the adjuster all the way out like that the geometry of all the other components is getting on the ragged edge.
Drums aren't bad for your Falcon . Here's a link.

Ford Falcon Brake Drum - Drum Brakes - Pronto Centric - 1963 1962 1969 1961 1960 1966 1968 1964 63 62 69 61 60 66 68 64 - PartsGeek.com

Now a lot of guys would harp on how we suggested that the system be converted to a much safer duel brake system (probably would have been a wash cost wise between the conversion cost and the cleaning of Nick's shorts and seat covers) but not me. No, I'm way to nice of a guy to start the "I told you so" chant.

Brian, I'm not sure your drums are out of spec, but I would agree that the shoes might not be correct for the Falcon. It appears to me that the adjuster slipped out of place, which then allowed the wheel cylinder to come apart. I'd probably reassemble that brake setup, and look closely at the retaining pins/springs to ensure they are not cocked at an angle. I'd also compare the shoes on that side to the other side, to see if they have the same shaped recess for the adjuster to sit in. I'd go back to the parts store and have them pull a set of shoes off the shelf, and compare what you have to another set also. It could be they got the wrong year shoes in the box.

Sure feels good to get back to the weekly cruise routine! Hasn't started here yet, even though temperatures have been hitting high 80's here!

Bottom line, I don't think those are the correct shoe frames for the Falcon. Rebuilt shoe frames can fit thousands of applications by SIZE but not have the correct holes/spacing/geometry for every vehicle they supposedly "fit".
That part of the shoe wasn't modified by me. But I went out there this morning and looked and yes, that looks very funky. But looking at new ones on line, most looked like that! Shoes can be so different, others have a very defined deep place for the adjuster to ride.

Yeah, all good stuff, thanks guys.

I will start with that basic idea right there. As far as I can tell on line they are the same. They matched what I had so that is of course why I used them. The hardware kit didn't match on a few parts but it made sense at the time. I know originally it had two different adjusters on the front and I replaced them both with this one matching one of them, The other one was wrong, from what I was told at the time.

I went out in to my garage and looked at one of my old Motors manuals and it shows a shoe retracting assist spring across the shoes mounted underneath the wheel cylinder. I don't know if this spring should be on yours or not but I'm sure it's on my grandson's 66 Mustang. Could be what's causing your problem.

Can you post a photo of that? I know that this is a 6 cyl and has different brakes, but I am not sure what is different other than size.

This is what I found and might not be applicable. Do you 4 or 5 wheel lugs? 6 bangers had smaller drums and shoes and the hardware is somewhat different. I'm thinking you might have mixed parts.

I am lost, the only thing it can be is the adjuster is wrong. But even then it doesn't account for it falling out. Something just hit me, I did need to file out the slot a little so they would fit over the shoe! What I have is a 9.060 drum (with my crude measurements of 9 1/16") leaving a little room to the limit of 9.090 cast on the drum. The shoes fit the drum perfectly as you can see in the first photo. The second photo is where the self adjuster fits, it's not very good of a "holder" for that adjuster. But that's all I see. The springs were tight as hell. That is all I can see. Of course it could be one of the things you guys mentioned that I will continue to study it. I plan on getting by the parts store tomorrow and seeing if the adjusters they have in stock now are the same.





Any ideas?

Brian

I am just thinking with my typing finger here. Is it possable that the shoes are not properly being anckored in place. That would allow them to try to rotate pushing one side of the wheel cylinder in and allowing the other side to be pushed out? Does the top anchor pin look ok?

I think you're on to something there Brian! I wish I still had all the parts I removed off my Falcon when I changed the front suspension! The '66 Mustang mentioned above is not the same as your Falcon. Falcons also changed in 1964 when they went to the new body style.
Just in case I have any parts in my scrap bin, I'll go look and see if the adjusters might be there. If so I can measure them, or just send them to you.

Those shoes are meant to have a retainer spring in the 2 holes just above the adjuster like a GM application. That will keep the end from slipping up out of that shallow slot.

From an old Chilton's. What year and power assist or manual? A sidebar says that they switched to tamdem brakes in '67.
