Moderator, please delete the wanted post. Ended up dismantling the precharge pump and gave it a good clean and re-bled the system. All in working order.

I did. Here are some of the precharge pump. It was taken apart and brushes were cleaned. The picture with the blue arrow is after cleaning. I have a video as well of the bleed. I will have to look for it.

I would love to see a full detailed how to on this to show the electrical side of things
and cleaning the old gunky brake fluid out of the pump where the proper bleeding
procedure has not been done in years.
This would be of benifit to so many models of this era
With some of the high pressures involved its not something to just steam into

As an aside, if you're looking to clean a motor commutator, don't use an abrasive such as emery cloth. Why? The small particles of the abrasive will come off of the paper backing while you're using it and can become embedded in the soft copper of the commutator bars. This turns the bars into little grinding wheels which will wear the brushes down quickly.

There are commutator stones that can be used on the commutator bars with the armature mounted in an electric drill. That's the preferred method.
