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

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

              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 â??Tech Talkâ??, 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 â?? donâ??t
              rely on whatever the package says â?? 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 <u>all </u>the
              solvent out of the bearings, preferably using compressed
              air, but paper towel and perhaps a hair dryer would work,

                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

                Did I miss something?  That kind of glosses the assembly
