... sorry to havee been a bit confusing in my earlier reply ... I was in a
bit of a hurry ... as I am now!  :)  The reservoir that mounts tot he brake
M/C has two individual chambers ... one that feeds each half of the M/C.
When you open the cap you have direct access to the rear chamber ... all the
way down to the back side of the nipple that plugs into the grommet.  You
don't have anywhere near this access to the front chamber ... so you either
live with the little bit of fluid there when bleeding, or you pull the
reservoir off the M/C and drip brake fluid about under the hood if you're
not careful ...
