Brake drum issue legality

Did someone recently replace shoes and not drums, or didn't bother to cut drums?

 

If you think about it, the 115,00 miles of wear and use has made metal particles erode.
Since the drum is open in back, it is only logical the particles, and dirt and rocks,
(dead birds, and little critters too,) would migrate or roll to the outer edge + fall out.
Open and close brakes - and these particles that migrate or roll to the open side are trapped for a time under the brake shoe. So your product is wear thats uneaven.

 

And is that your picture - or Frank Zappa.
Saw him in Fillmore East like 1969 or so. Wow.

 

The wear on the drum cannot be more than .120 over the original size of the drum. In the old days with asbestos brakes the shoes used to wear and the drums didn't. With a whole host of materials used in brake shoes these days, I find my drums wearing out much faster, usually replacing the drums every other brake job. They are cheap. One of the more prolific posters around here is Scalemaster who routinely checks drum diameters with a tool the enforcement community has.
I don't know what the out of service criteria is. 110,000 miles seems to be premature, but don't know the particulars.
