[200q20v] just out of curiosity (UFO question)...

[Phil Rose]

Yesterday I was kibbitzing with a local Audi wrench (small-shop guy who
likes to chat) while he completed a CV boot replacement on a '90 V8. While
I was examining the UFO brake I noticed a strange-looking appendage (seemed
to be stainless) which stuck out horizontally near the top (inside) end of
the caliper. It has a thin shaft (tube?) that's about 1.5" long and it
terminates in round, flat-ended "knob" of about 3/4" diameter.

"Whazzzaaaat?", I asked.

He smiled, and replied, "You tell me. I've been wondering for years about
that thing."

I looked in my Bentley and could see the "thing" clearly drawn in several
UFO caliper diagrams, but there didn't seem to be any notation as to it's
name or function.

Anyone have a clue?
