One more thing ...
I've never liked the little felt bushes that go on the end of the shoe
standoffs; they deteriorate as soon as they're installed (and are
usually a gooey mess when you replace them). But, I ordered a set from
Tom's Import Toys, but instead Tom sent some fiber tubing cut into short
pieces. These fit perfectly and firmly over the standoffs, and you can
place a little grease on the end and expect it to stay there. I don't
know a source, the tubing looks like it could be small fuel line, but
it's only fiber with no rubber or other lining.

Here's the sequence of installation that caused me the least

<br>
1) LIGHTLY grease all moving/sliding parts, including the

<br>
2) Insert cylinder into its slot<br>

3) Slide the spring plate, with hooks pointed toward the

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>

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>
