Fred,
I=92ve got a used and cleaned up complete slave cylinder (caliper, pads and
 bolts).
I also have a spare bleed screw.
In my bag of a  mono brake I took apart and prepped for a spare is an O rin
g also which appears to be 1 3/8 ID 1 5/8 inch OD, 1/8 inch thick O ring is
 the seal for the piston.
The photos I sent to your personal email.
Bud

Bud=85forgive me, but when I look at the exploded view, 29-8, in the XS Bui
ld Manual, I don=92t see any hint that the Europa =93Brake Slave Cylinder L
G23" breaks down into pieces or contains an O ring.

>From what you=92ve written, I=92m thinking that if I remove the two AN4H-15
A bolts, doing so will allow me access to the O ring that you=92ve mentione
d=85Please confirm=85or=85Is the puck, or slave cylinder, just a block with
 a hole in it?=85and 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 pe
r the manual, wrapped the bleeder screw in PTFE tape.

BTW, I=92ve really trashed the hex portion of the bleeder screw, so I=92d l
ove to find a replacement.

Fred,
I've had good luck simply buffing out the pucks and the caliper.  It's just
 aluminum, and rarely does the puck get damaged. It does get a bit rough fr
om 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 jewe
lers rouge after a sanding with 1000 grit paper to shine it up.  O rings ar
e tough to find.  Especially the square edged ones.  I'm no help there.

I have no spare calipers as I have a Europa mono in the shop with some seri
ous gear/brake issues and may have to rebuild everything!  I find it odd th
at the gear and brakes passed inspection for the last two annuals in this c
ondition.

I'm afraid if your disk and caliper are in bad shape the cost of replacemen
ts is getting harder.  Consider the Berringer Brake unit as a long term sol
ution.  I'm just too old to worry about long term, so I spend the time and 
buff and clean.

Best Regards,
Bud Yerly

Gentlemen,

I=92m hoping to source a mono brake puck here in the US, perhaps from someo
ne who=92s converted to trigger.

Please let me know if anyone might have one for sale,

Fred
