it's normal for a backing plate to flex a little like that..
like if you lever a little with a screw driver between backing plate and
drum.
the force on the backing plate is all rotational.
No need for it to be rigid in plane.
Of dozens of types of cars I have worked on for decades , drum brake
backing plates are always like that.
None are rigid in plane.
Might even help the shoes self-align a bit.
I don't think it matters too much what they are painted with, as long as
there is decent corrosion protection.
I've seen them rust right through on a vanagon ..swiss cheese.
I *always* paint my drums with High Temp flat black paint. Keeps 'em
from rusting pretty nicely.
the GW drums look pretty nice !
Might even get some someday.
re quality of drums ..
my 'favourite' situation I've seen ....A person I know did a lot of
research and bought an 83 Westy from a well-known Vanagon specialist
company ...
I ended up working on it ..and find a brand new right rear drum that is
very out of round ..
the way I like to get drums to pop off the flange is hit the edge with a
hammer ..
if they are not too stuck on the lip of the flange they'll jump right
off very nicely that way.
this particular drum had a 3 inch long balancing weight on it ..
unusually large,
one medium tap on the edge of the drum and that weight fell right off.
Talk about a cheap part !
