 Topic: Rusty brake pins...
Posted: 08 Feb 2025 at 9:11am |
Just a couple of photos of the remains of the brake pins & toggle from the left side of the '41. This is the "good" side in that the toggle arm isn't rotted completely off...
There's a chunk of drum that's rusted right off the inner edge so probably needs new drums, that it isn't going to get any time soon!
Also, the rear housing seal must be that bad from the amount of grease mixed with the mouse nest inside the "trumpet" that it's actually saved the hinge on the brake band, which broke loose and came back round with a clean & working some oil into it.
The friction material is pretty horrible but mostly in one piece so plan now is to remake the rotted off ends of the bands & rivet that back on (paying mind to the fact that it will 150% be full of asbestos, I believe it's original) UNLESS I can find a source of friction material to suit for less than about £10. All it needs is to be able to have SOME brake, better than zero.
Here's hoping the diff seal is as bad on the right side so I can save that hinge too! Friction material actually looks better that side...

If it had 3 point, I'd swear this poor thing was a yard scraper all it's life!
Ever seen the edge of the drum rotted right off too? lol

Seen drums that had deep score marks and probably 1/8 inch too small in diameter.. Have busted a couple getting them off... but never seen one ROT in place..
you got enough left to replace the linkage and get the brake band to grab the old drums ?

Will have to try and get a measurement of the drums, but the left side is DEEPLY pitted rather than scored, I'd bet they're way undersize.
Should have enough here to be able to remake this side brake band "custom" & have enough adjustment. Other side I haven't looked closely at yet but I know part of the linkage is flat out missing & the toggle is rotted off. Will be a huge rig up if I even get both sides to work (I would like to though).
I think the biggest surprise to me really, is that anything even came apart/moved back here without resorting to heat/power tools. (EDIT- I should add the caveat here, no heat/power tools YET! hopefully not already activated Murphy & his law).

Here's the right side toggle, now I look at it the pins & drum actually look better than the left side so there may be some hope after all.
Can't find a spec for drum minimum size (I've only got an IT book don't think they give the specs) but roughly measuring with a tape through the hole I'd say the left drum is approximately 5 5/8" diameter at the most, maybe 5 1/2". Would imagine they started at 6" new? Pretty darn bad anyway, feels like the friction surface is maybe 3/32" thickness.

Yeah they're not good at all. Probably just run what I brung until they actually break apart & at that point consider whether I can invest in replacement drums & bands.
The old girl is starting to grow on me quite a bit, she's trying her best to work with me & my hack fixes so it's just a case of if I end up using her enough to justify real repairs. In other news though, we may be moving to a more rural area this year so that could facilitate more opportunities to get in the saddle. Here's hoping!

There is a certain rewarding skill to driving anything with no brakes "safely", and being a low geared tractor makes them even more "optional" but if I'm going to take this thing on the road (and I fully intend to!) then I'd much rather have more than the outsized front tires rubbing the spindle housing to help stop the thing! (not to mention being able to turn on a dime)

Haha don't tempt me... Actually don't have any spare in "the stash" though. Maybe once I 1.9 turbo diesel swap the thing!

ekjdm14, Here is your goal: Just teasing:
Yours has some rust for sure. Good luck.
I still have a bunch of work to do on our CA. Brakes are one of my goals! Regards, Chris and Cheryl

Haha Chris, your post was one I referred to while searching on brakes. Certainly looks a lot nicer than my toy has much chance of doing, maybe I'll restore her one day just because it's so much of a challenge!
Actually, now looking at the photo of the new drum I'm seeing how much meat is supposed to be on them. Mine are finished with a capital F lol those are at least 3/8" if not 1/2" thick mine are like 3/32"!
At least doing yours properly with new, actual, parts will make it a bit less of a struggle train. I bet you've got shiny new "Rick" brake bands too!

Many years ago a neighbor had an old Model B Allis-Chalmers that had hand brakes; they were awkward to manipulate but they did stop the tractor. Given your already proven propensity for innovation, I am wondering if some sort of 'wagon wheel' type brake could be rigged up using wooden blocks to rub on the existing brake drums.
It certainly would not be like having proper brakes, but it may well be better than what you have now.

Hey Dan
Was just wondering, with all those so badly rusted components on your 'B', you must do some Diving in your Spare Time, and found that 'B' at the bottom of the English Channel! LOL
May have rolled off an Aircraft Carrier during WWII.
According to my father, that was the case for a few Army Jeeps.

Considering it hasn't got 3 point so scraper duties pretty much ruled out, I think sea water may have had a hand in it's condition yes! Given the worst of the rot is the back end though & the front appears to have survived much better, I have to wonder if it served as a launch vehicle for a fishing boat or similar. That'd explain the azz end being so bad.
Les, wooden brakes did cross my mind but having extricated the remains of the left band & found the hinge to actually be salvageable thanks presumably to a bad diff seal, I've made a start on rebuilding a brake band. For now I've got the loops made up & the repair sections tacked onto the hinge, had a good root around in the "mouse door" with a pry bar and scooped out at least a pound of grease-soaked nest & asbestos & managed to fish the band around for a preliminary fit up before it went dark. Considering the state of the drum I may actually line the band with wood while it "wears back in". Either that or add offcuts from the angle iron to it & run metal on metal.
EDIT- actually, maybe the linings ought to be strips of old car tire. I think that'd work pretty well on the bad drums & replacements would be easy to find on any back road!

And, just like that, we have some semblance of brake on the left side now. I did reuse the original linings for the moment but there's plenty of adjustment in there to be able to go to tire strips when that wears away.
The right side promises to be more of a bear to get sorted, have to make a toggle for that side too. Hopefully get some metal for the rim soon & have her back on all 4 wheels again.
