Back from the road trip and spent a bit more time with the 3800.
Get the fork yanked and start to pull the caliper when I see this.
One arm of the caliper had broken off and the PO had done this. No wonder it didn't stop. A redneck repair if I've ever seen one. On the bright side, I can use a section of the 'repair' and weld it to the caliper arm the correct way.
