Yes, the old brushes were completely worn out. Note that the ramp on
the new brush slopes the wrong way; I can't be sure about the old
one.

The brush wore to the point where its pigtail ran into the end of its
clearance slot, so it could no longer be forced against the
commutator. Once that happens, it will arc, and that eats up the
copper, as you see in your photo.
I can fix the commutator, correct the ramp on the brushes, and fix
anything else that becomes apparent when I take it apart and test it.
