[T3] Houston, we have ignition!

Just for information, if the rear seal does leak, the fluid escapes into the
front bulkhead and then into the floor-pan tunnel and eventually will find
its way to the floor drain at the rear of the tunnel.  Since '67 there's  a
rubber drain valve here (like the one on the crankcase vent drain, but not
exactly the same), but it can be knocked off if the car goes over long grass
or rutted tracks. 
It can be a bit surprising when looking for a fluid leak to not find one,
when the reservoir level is dropping.  It's surprised me once, until I
realised where the fluid was going!

The boot over the mouth of the MC has a small hole on one side. That hole is
supposed to face down, so that brake fluid can get out if the first seal
starts to leak. I suppose VW thought it was important for you to perhaps
smell the brake fluid and do something about it, rather than let the fluid
just accumulate inside the boot.

It's the hole that lets leaky brake fluid "weep" out.
