Certainly 4 are shown in my parts book, so suitable for MkIIs. Shaped =
and show as a fit between cylinder and bulkhead.=20

Surely the fact there are 4 indicates that they are indeed meant as some =
form of adjustment shim.

In my drawer of brake and clutch related =E2=80=9Cuseful stuff=E2=80=9D =
there was an apparently unused brake master cylinder with an adjustable =
push rod. The shaft=E2=80=99s rod was threaded and screwed in and out of =
the clevis pin end and could be locked with a nut.

Perhaps the cheap(er) shims replaced the more expensive cylinder?

Adjusting the shaft in situ would be an absolute nightmare for anyone =
who wasn=E2=80=99t whippet thin and possessed of short arms with many =
joints.

Who knows what the purpose of the Master Cylinder Packing Piece is? =
There are 4 on the brake master cylinder and none on the clutch master =
cylinder. As far as I can tell the packing piece would reduce the =
distance the push rod can travel into the bore of the master cylinder. =
Is there an adjustment for the brake pedal and push rod that you use =
these packing pieces to set?

=20

The workshop manual specifically mentions =E2=80=9Cnot forgetting to fit =
the packing washer first=E2=80=9D as part of the brake master cylinder =
installation.
