Default '99 S70 - Seized Bleeder Screws

Was wondering how to remove seized bleeders on these cars. We were able to free up the passenger rear bleeder and successfully flush all the old fluid out of the line. Things got worse when switching to driver side rear. Broke 2 lug nuts just taking the wheel off and to make matters worse, the bleeder is rusted on good!

It's not stripped or anything, but vice grips wouldn't get it off. Just want to hear some methods for potentially getting these things off. Oh yeah, and we have soaked it in PB Blaster before trying to take it off to begin with.

Any help or tips are appreciated in order to avoid breaking the nipple and screw off and being screwed LITERALLY.

Thanks!

Just curious, do you have the ideal tool for this? A proper sized hard six pointed socket would be my first choice. All bleeder screws have that issue. if may be too late for that if you've been to the vice grips.

So whatever you do to get the ideal and highest possible torque applied, you do that. the only other things you have to play with now is heat and penetrating oil. The best penetrating oil in the world is a 50/50 mixture of transmission fluid and mineral spirits. Some people use transmission fluid and acetone. Kroil is about as good as that also. PB blaster is pretty good. You might have to spray it every day for a week. If you don't have time for that just replace the caliper, I guess.

If you are only trying to crack them to do a fluid flush, then your best choice might be to stop now and not do it.
