Wagner Comex woven brake liner friction differences

[ctlikon0712]

Here is a photo of some Wagner Comex liners, notice the note about 4 X Low, and 4 X Standard friction. I’m using cast iron drums. Original spoked in front and I haven’t purchased the rears yet.
How were these supposed to be configured? Low in the rear and standard in the front? Since by the 50's, drivers were accustomed to a front biased braking system.....? I have searched the internet for any info and can’t find anything. I’m hoping someone remembers these and where to install them.
Also I have some old hollow Rivets. I’m not sure what the proper ones are for the model A application. Does anyone know the proper size for them? I know that typically you want one and a half times the diameter protruding past the material before you swage them….. Not sure with the soft liner and hard shoe if that is still true.

Anyone?

Can't help, but is there a particular reason you're determined to use those linings vs new that's available today??

No, just that I have them and that they are in great shape. I'm not so sure that they are a different material than those used today, just that one set of 4 has more bronz or metal woven into the fiber.......
Thanks for posting though

Craig,

I can see that in a "Duo-Servo" (hydraulic) brake system with a primary and
secondary shoe...I believe the linings are of different material, for that set-up.
I don't why the Model A would have to have it....I need to think about that.

I'd guess the heavy duty would go on the rear since the Model A brake pressure is biased to the rear, 60% rear, 40% front.

Thanks Tom, I thought that was a possibility also but these liners are a bit newer and thought that maybe they had changed the material because of the "newer" conventional thinking on brakes. lol Ya know the 40's and newer. J I also noticed that the brand is COMAX not COMEX like I had first wrote. I researched and found more but it’s all EBAY stuff, not any reference material I can read...
