also since your going to have the fluid drained anti-seize the bleeder
screws.  people might think i'm nuts and that it will contaminate the
hydraulic system but i have been doing it for years with no ill effects.
what you need to realize is that the bleeder screw seats on the tip and
the threads don't really come in contact with the hydraulic circuits.  also
the threads are a bit removed from the tip up the shaft of the bleeder
screw.  so as the screw is screwed in the anti-seize is displaced to a
degree upwards on the bleeder screw.  all that said i leave the last
thread of the bleeder screw threads free of anti-seize just as a
precaution.

i also recommend the wrench and tapping method mentioned earlier.  i never
try to turn any fastner that was exposed to the weather and is not known
to be anti-seized without first tapping on it any more.
