<p class=MsoNormal><font size=2 color=navy face=Arial><span style='font-size:
10.0pt;font-family:Arial;color:navy'>There are actually several different
variations on the 10" brakes, you're looking at the least well documented
version. If someone has a parts diagram for it, I would like to have a
copy! (The SPC only lists the parts, the illustrations are for other
versions without that support pin. I'm trying to add some of the missing
illustrations to the SPC.)<o:p></o:p></span></font></p>

<p class=MsoNormal><font size=2 color=navy face=Arial><span style='font-size:
10.0pt;font-family:Arial;color:navy'>The pin just abuts the shoe, and in fact
holds it in alignment with the drum. I believe there should be a little
felt ring on the end (P/N 105671) to hold a bit of lubricant at that point.
If the pin rusts and wears enough, you can get a strange "clunk" that
only happens a few seconds after you take your foot off the brakes after
stopping. The worn pin lets the shoes tilt inward, but they walk out to
match the drum when you make a stop. Then when released, fall back
against the pins. Took me a long time to find that one!<o:p></o:p></span></font></p>

<p class=MsoNormal><font size=2 color=navy face=Arial><span style='font-size:
10.0pt;font-family:Arial;color:navy'>IIRC the hole was to adjust the brakes,
when that same drum (same P/N) was used on Lockheed front brakes for TR2 and
early TR3. No use on a car with Girling brakes that I've found.<o:p></o:p></span></font></p>

assume to help keep out dirt and water, but it doesn't seem to be listed in the
SPC.<o:p></o:p></span></font></p>

<p class=MsoNormal><font size=2 face=Calibri><span style='font-size:11.0pt'>The
smaller brakes have a pin which comes through the shoes and is held in place
with a clip. The 10” set-up appears to have a pin which screws in
from the outside and is secured with a nut. Does this pin abut against
the shoe or should it go through ?<o:p></o:p></span></font></p>
