Agreed! I hate that silly sliding rear drum brake cylinder =

"... disk brakes are substantially different to work on than drums ..."
ARGH ... should be 'substantially EASIER to work on than drums ...'

Yes, you do need the back plate, and I would ensure that the rubber seal =
that presses onto its inside edge is also in place. If you =
don=E2=80=99t have them (they deteriorate over time), they are available =
from the usual suppliers. You are right the drawings on assembly are =
ambiguous =E2=80=93 even in the parts book. I put mine on the way they =
came off, and it has been five years since I last did them. I recall it =
is relatively obvious but I always note the assembly when taking it =
apart. I don=E2=80=99t trust my memory to describe it =E2=80=93 I will =
leave that to others.
=20
Don=E2=80=99t be intimidated by setting up the front bearings, it really =
is not that hard at all and the factory workshop manual provides good =
guidance. Norm Nock also has a description in his book =E2=80=9CTech =
Talk=E2=80=9D, which is still available from British Car Specialists. =
It is important to have a selection of a few shims handy. When I last =
did mine, I followed the workshop procedure and when I got it almost =
perfect added/subtracted shims and spun the hub by hand, feeling for =
drag until I was satisfied that the bearings were running free, but that =
there was absolutely no end- play in them. Some people use a dial =
gauge to measure end-float, but I think it is unnecessary and have =
always (i.e., for over 40 years), done it by feel. Make sure when you =
are setting up the bearings that you have some good calipers (i.e., =
decent metal ones, not plastic), or use a micrometer, to check the shim =
thicknesses =E2=80=93 don=E2=80=99t rely on whatever the package says =
=E2=80=93 measure them! Do not grease the bearings when setting them =
up. I sprayed mine with some WD40 to provide some lubrication just =
while setting them up as you should not spin dry bearings, but a very =
light oil (3 in 1?) would probably be OK. When you are satisfied with =
the set up, then disassemble, noting the shims you used, wash out the =
light oil you used with a solvent, then pack the bearings, install the =
seal and put it all back together. Be sure to dry all the solvent out =
of the bearings, preferably using compressed air, but paper towel and =
perhaps a hair dryer would work, before packing with grease.=20
=20
Getting this right is really important as it substantially adds to the =
strength of the front axle assemble and minimizes cracking and failure =
of the stub axle.

Put on some music, have a beer, and enjoy it.

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 =
