GO SLOW. If you ram the drill through the bottom of the broken bleeder,
you can ruin the seat in the caliper. Use a drill slightly larger than the
hole in the
broken part, and be careful to stay square with it. The old hole should help
there.

The heat and friction of drilling may loosen it enough to get an ez-out in
there to
unscrew it. Use lots of Liquid Wrench or WD-40, etc while you drill.

If you have a bottoming tap of the right size, you can drill the bleeder out
to the
diameter of the bottoms of the threads on the new part, then chase the
threads in
the caliper. If you mess up, at least you are no worse off than now.. If you
do this
make sure to disassemble the part and flush out any chips!

In an emergency, you can 'bleed' the system by loosening the hose or pipe to the
broken cylinder, but this is only to let you limp until you can do it right, as
all the air and crappy fluid in the caliper now just stays there..
