Broken bleed screw

[scott miller]

Got the screw out with a big screw extractor, but it's a mess in there.  Had
to drill the tip out, it didn't come with the threads.  The threads are
untouched, but rusty all the way to the end, so I can't get the new bleed
screw in all the way to seat.  How to clean the threads?  A metric bottoming
tap is near impossible to find.  Perhaps I'll buy a tap and grind the tip
off.  More time and $.  Any other thoughts out there?

This is the bigger size bleed screw on rear Girling caliper, what size
thread is it?

I wonder how much crud I've introduced into the piston at this point, for a
$98 caliper.
