Here's a short video of the cylinder moving (complete with 80s
soundtrack and modern 'shaky cam'). Pic shows the bevel on the dust
cover that I think proves this is the correct order of installation.<br>
<br>
Here's the sequence of installation that caused me the least
frustration:<br>
<br>
1) LIGHTLY grease all moving/sliding parts, including the adjuster
cam and spreaders and the shaft that the handbrake lever pivots on<br>
<br>
2) Insert cylinder into its slot<br>
<br>
3) Slide the spring plate, with hooks pointed toward the diff, into
the slot on the cylinder from above as manual shows<br>
<br>
4) Insert the handbrake lever through its slot on the backplate from
the outside<br>
<br>
5) Lift the cylinder a little with a screwdriver and slide the
handbrake pivot shaft into its notches on the cylinder (the spring
plate allows this)<br>
<br>
6) Start working the flat retaining plate with the notches into the
slot on the cylinder on top of the spring plate. I tapped it in; it
would help if someone held the handbrake lever out in its actuated
state to prevent the spring plate from retreating from the flat
plate (it might be possible to squeeze them together with a large
set of channellocks). Make sure the little hooks on the spring plate
engage the notches on the flat plate.<br>
<br>
7) Work the rubber boot/dust cover over the handbrake lever and
around and under the retaining plates, with the beveled edge sliding
under the plates (see vid).<br>
<br>
8) Wipe off any excess grease (it doesn't go well with brake
material)<br>
<br>
Credit where due: I'm often (always) disappointed with the quality
of aftermarket rubber products, but the dust covers I got from Moss
are not only molded and cut perfectly, but seem to be made of a
tough rubber that should actually hold up (it's almost a soft
plastic).<br>
<br>

<br>
ps. This is as much for my benefit, as I seem to have to do this job
every decade or so, and have to start from scratch procedure-wise
every time.<br>

I just spent several hours on my back on a greasy floor
working on my <br>
BN2's rear drums. I didn't see any text in the shop manual
explaining <br>
installation; most I found was a pic in the Moss catalog
showing that <br>
the curved spring, with the 'hooks,' should be installed above
the <br>
cylinder (between the cylinder and the handbrake lever).
First, I <br>
installed the flat plate against the backing plate with the
spring plate <br>
on top of it. Not only would the cylinder not move
freely--which enables <br>
the self-energizing aspect of the brakes--but the rubber dust
boot had <br>
nothing to hold it in place. I then reversed the installation;
i.e. the <br>
spring plate was still above the cylinder, but under the flat
plate <br>
(hooks up). This way the cylinder would slide smoothly and
easily, which <br>
makes sense because there is less contact area, but the rubber
boot, <br>
which is beveled on the inner part fit naturally under the
flat plate <br>
and would stay in place when vigorously sliding the cylinder <br>
back-and-forth. Contact surfaces were lightly greased.<br>
<br>
Short answer: the cylinder should slide smoothly and easily;
otherwise <br>
the self-energizing feature could be defeated, and the
cylinder could be <br>
stuck in the expanded position, which could explain your
non-retracting <br>
problem.<br>
