It can be a "stiff" pull.  Make sure you don't angle your pressure.  You
can break off the old plastic that passes through the donut seals.  Most of
the brake fluid will run out of the openings in the reservoir, I
believe.  I got as much of the brake fluid out as I could with a turkey
baster first.  Still made somewhat of a mess. Have a bucket of water
available to rinse the fluid off  the engine compartment after you get the
reservoir resealed.   I think I put a bunch of towels under the master
cylinder when I did the second one.  Made cleaning up the mess easier.
