I think the new lining thickness is normally 3/16".
(I just measured several that I have which are hardly used and they're 3/16")
The best case scenario though is to buy and fit oversize linings, and then have them skimmed down on a lathe
with the shoes wedged about 1/32" - 1/16" apart. -This means that when the lever is pulled and the shoes open up a bit,
they're dead round, to make full contact with the drum.
(Or just fit new linings, then, eventually, by the time you've ascended to the great workshop in the sky and the
linings have had 5000 miles to bed in, they'll be good).
