The Shimano BL-M615 Brake Lever - clamp fractured. (see picture - red circle)
No repair could be done, just a replacement.
I had my local bike shop order a replacement.
The replacement is not an identical match
... but close and it works awesome!
on advise from fellow rider, I now leave mine loose enough so they are able to move with impact instead of break. They still require a considerable amount of force to move so they stay in place under normal circumstances. Good to know ... Better to try!
