This implies it was running on a single brush set. If all four were working, and one failed, you would still keep going at a reduced power. If you weren't pushing it hard, it may not be noticed much, just a bit sluggish.
When you lost the second brush, you lost the lot.... so thats why I still think brush... BUT
If you were already 10 degrees advanced, another 6 would be pushing it, and I would expect arcing under heavy load/high speed. If we had extra advance AND were missing a brush, were doomed under medium load and for full power... well.....
