Zimmerman drums.

Yes I did wonder a out possibility of wearing out the lug nuts;
I had read your posts about that.
The image was a close up cropped. So maybe pitting is accentuated?

I did what I thought was due diligence inspecting shoe condition after
allowing the shoes to bed in a little.

Turns out that mark was a small (less than 1/2" long)  casting flaw.

How can one tell when a wheel fastener seat is worn beyond spec?

I will stop posting about my brakes!    ;)
