Brake bleed didn't take. 120-130

The DOT number rating system pertains ONLY to physical properties (heat soak, water absorbtion, performance, etc.) At the time of developing the "5" level silicone was the only material that could perform at that level. Well, now glycol based stuff can, so in order to minimize confusion for us consumers they coined "5.1" to clue you in that it meets DOT 5 specs (except for water absorbtion) but ISN'T REALLY THE SAME STUFF. For bureaucrats I thought it was a pretty good solution.

By the bye, I also use silicone DOT 5 and like it immensely.

I disagree slightly on the every bit of old fluid out. The old fluid retains water so any pockets of old fluid will lead to corrosion localized at those points. System will still operate fine but boiling point of fluid will degrade wherever old, water soaked fluid remains.

So, it needs to come out but the system will still operate in the meantime.

Sounds like a bad MC to me.
