Many thanks Tom, once again. Of the dozens of pictures of calipers in 
the factory manual CD and Clymer 2004, only picture is page 618, fig 
196 in Clymer,

Like a speedbleeder or some checkvalve mechanism? Is there any way to 
attach a MityVac to the thing?

For removal, I suppose heating with a cigarette-lighter-type butane 
torch would be good. Unaccustomed as I am to newish bikes, I am finding 
many of the screws on my 1999 R1100S to be rather tight... PIA.

1. At the best, benefit of SS is mainly to looks (which is why I opted 
for thinner Spiegler line); braking benefit (which really is there) 
depends on how old and how long is the rubber being replaced. BMW has a 
taste for grotesque brake line runs in ugly rubber - are they too cheap 
to use that trick thin hydraulic clutch line on the brake lines (maybe 
it doesn't meet stds for more critical brake use?)?

2. Often takes a few days to get all the bubbles out and so hard to 
make a trustworthy simultaneous before-and-after comparison.

3. Geeez, odd to hear you say that, Bob. I thought ALL mods a person 
does themself always result in immense improvements!
