I am about to give up on attempts to rotate the cable end externally... I cannot think of any ways to force rotation past its current sticking point to expose the end. I have found references to a few people having succeeded in disassembly/re-assembly, but most seem to end in disaster and spring loaded pieces flying....
I am considering drilling a hole thru the outside brake handle body to (hopefully) expose the cable end in its current position... kinda shooting in the dark, so I thought i would run this by the group to see if anyone has tried this? Sounds crazy, but may be safer than attempting disassembly?!
