Budforgive me, but when I look at the exploded view, 29-8, in 
the XS Build Manual, I don=99t see any hint that the Europa 
=9CBrake Slave Cylinder LG23" breaks down into pieces or contains 
an O ring. 

=46rom what you=99ve written, I=99m thinking that if I 
remove the two AN4H-15A bolts, doing so will allow me access to the O 
ring that you=99ve mentionedPlease confirmor
Is the puck, or slave cylinder, just a block with a hole in it?
and if so, where is this O ring?

Please forgive my ignorance.

My leak appears to be coming from the bleeder screw; however, I have, as 
per the manual, wrapped the bleeder screw in PTFE tape.

BTW, I=99ve really trashed the hex portion of the bleeder screw, 
so I=99d love to find a replacement.

just aluminum, and rarely does the puck get damaged. It does get a bit 
rough from corrosion.  A freshly smoothed caliper and puck with a new O 
ring seems to work well.  I use a cotton wheel on a Dremel type tool and 
some red jewelers rouge after a sanding with 1000 grit paper to shine it 
up.  O rings are tough to find.  Especially the square edged ones.  I'm 
no help there.

odd that the gear and brakes passed inspection for the last two annuals

spend the time and buff and clean.
