What is the consensus, Brass or Steel? MG

Here's what the encyclopedia says: http://www.mtfca.com/encyclo/A-B.htm#bushings
Apparently Ford thought it was so important with bronze there so he didn't change to steel until 1922, while the other bushings like in the spring shackles were changed to steel already in 1915.

I think I'll try teflon (PTFE) plastic bushings there some day - I like the idea not having to oil where it may leak into the brake. I have acetal (POM) plastic bushings for the spring shackles that works very nice, but Teflon can take heat better.

How much do you want to wear out your brake cams? The choice should be logical, and besides, no one can see them.

Thank you Larry, I only ask because the vendors offer both. Obviously with no oil hole the brass would be less aggressive on the cam shaft. But is it a big problem for one over the other. Knowing that steel was adapted in '22. I'm working on my late '12 rear end. Thanks to all for your input! MG

MG,

Whichever one you choose, it should last you a very long time. It's not a critical choice.

By the way, just because it might not have an oil hole, that doesn't mean it can't or shouldn't be oiled. Just put a few drops on the shaft, between the brake arm and the backing plate, and it'll get in there.

I think a better choice would be to use 'oilite' [sintered bronze] bush. These things are porous, you impregnate them with oil prior to fitting them, then they are self lubricated for life. Commonly used in starter motors etc.
