Ugly time with ABS Automated Bleed procedure via Tech 2 on my 2013 Escalade

[Geotrash]

well i got as far as getting new fluid in the master cylinder and system pressurized with the Power Bleeder...passenger rear bleeder screw is pretty much rusted in. Have been at this for almost 5 hours now. Cant get a good enough grip with vice grips to turn anything, only rounding the head some more. Caliper change time?

You could always soak it with penetrating oil and try again tomorrow. You’ll definitely want a new bleeder screw once you get the old one out. Best to have one on hand
