Stop in for a cup of coffee

Seems like pretty bizare failure. I don't care how hard you've driven it. Unless it was physically struck by something, I wouldn't expect any factory system to fail like that.

Excactly my thoughts as well. How the hell does a steel brake line just suddenly split open? There are no signs of corrosion on the lines and they have never been disturbed. Tomorrow I’m going to get a closer look and see which line it is and what might have happened.

It had to have been one feeding from the master cylinder into the ABS module. No warning light or code and the system lost pressure to all 4 wheels. It was operating fine earlier in the day.
