"... disk brakes are substantially different to work on than drums  ..."

ARGH ... should be 'substantially EASIER to work on than drums ...'

Can someone post a PDF of a service manual parts breakdown illustration =
of the front disc brakes of a 3000?  I see the picture in the Moss =
catalog, but I do not see the way the backplate attaches to the =
assembly.  Do I even need to attach the backplates?  Right now I have a =
bare swivel axle and need the assembly order of the brakes and extended =
splined hub.  As far as I can glean from all the info I have gathered so =
far, the caliper mounting plate should go on first, then the splined hub =
and disc assembly. (a major source of apprehension in itself)  After =
that I can assemble the caliper and brake line connections.  Did I miss =
something?  That kind of glosses the assembly over.  It's going to be =
more work than it sounds as I have never done anything other that drum =
brakes on the front of my Bugeye.  The splined hub installation with the =

finally cool enough nights to go back out into my garage and bust some =
knuckles.
