My 93 900ss has the 'right-way' up goldline rear caliper.
After removing it for a quick strip down I noticed that the bleed nipple was mounted towards the center the bike (the hose banjo bolt is in front of bleed bolt). Looking at pics of other bikes - I see this appears to be the standard arrangement.
SO...I think it would be better to have the bleed bolt closer to the outside to make bleeding easier. The bolt threads appear to be the same - will it make any difference which holes the bleed and banjo bolts are fitted ???
I guess the 'pressure' will feed through the caliper in the opposite direction but since it must reach both pistons anyway, does it make a difference.

Taa Daa - even found a pic...good old Yoyodyne
and yep - bleed nipple is at the rear.
