Had noticed the right hand brake cable was a bit loose the other day. Went to loosen the small outer aluminum ring before going to adjust it, and it was already loose. Went to thread the knurled cable adjuster out and it was wobbling in the hole - there was no more to let out.
Upon close examination it looked as though this cable adjuster was too loose in the handle, and the small outer ring was like double threaded or something. Never had issues with brake levers before.
Left hand brake looks okay and the outer ring is doing its thing - although it still loosens up. Probably need to double-nut these things.
Might get some photos tomorrow if I remember. The right hand brake cable is too loose, but can still stop when needed. it's that I am not over comfortable with a loose cable - and the adjusters going out of whack in a years time.
