I dug around the place and managed to gather up a pile of four different versions of, steel not cast, emergency brake shoes that were most likely made by that many different companies of the day.

The last one you posted would be the only one I would try to use...

The other ones don't seem to have enough reinforcement on the band area to keep the lining in firm contact with the drum...

Mind the asbestos Jay. There's certainly some there. Actually Adam I had the opposite feeling. That a more flexible shoe might conform better. They all seem to be of thicker metal than modern drum brake shoes which work quite well. Obviously none of these manufacturers though about 2 piece shoes.

Jay: the thick set in the bottom photo, are they split and held together by the loop?

Charlie, by making the shoes with steel as opposed to cast iron, there was no need to be concerned with flexing in use. Steel flexes. Cast iron shoes do not flex. Cast iron is used where flexing needs to be eliminated, eg. best quality vices and English wheels. Cast iron brake shoes need to be two piece to avoid the possibility of breakage due to induced flexing.

Looks like all those were making pretty good drum contact going by material left. KGB

Charlie, I believe so.

I have two shoes similar to the bottom photo that Jay posted. They are rolled from channel iron stock, but one has a taller lip than the other. Other than that, they are nearly identical. Maybe an early and later design? I have no idea who was the manufacturer of either of them. Dave

My experience has been that the cast iron shoes apply better pressure against the drums and work better. I have tried to use a couple of the rolled flat stock shoes, and found they did not work well at all. However, I will add that I did not make a serious effort to maximize their adjustment.
I also used one set of the bent-channel steel shoes. They worked okay, also without maximizing the adjustment. In more recent years, I have only used the cast iron shoes. Enlarging the cam to maximize the adjustment can make them work well.

I have a few of the rolled flat shoes. Since I believe their big issue for working well is a lack of rigidity, I have been toying with the idea of brazing some steel rod inside.
Anybody have any thoughts on that? David D?
Thank you Jay!
Drive carefully, and enjoy the New Year! W2

Fellows, I have seen a number of steel shoes similar to those shown. I will never use the type with the bent steel cam faces. The action of the cam drives one side of the shoe out against the drum. The other side is dragged in towards the centre. These steel shoes can and do bend inwards and loose all braking effect. I suspect two of the ones shown are heading in this direction.

Those with the cast iron cam faces are a much better proposition.

Hope this helps.
