In the process of getting the slack out of my rear brake cable, the "cap" on the insulated part of the cable pulled out of the barrel adjuster. While monkeying around trying to get that part of the cable to "catch" back inside, I backed the barrel adjuster all the way out of the handle and can't seem to get it back in--I may have stripped the threads. The brake is working fine; I went for a short ride and had no issues with it. My concern is that not having the cable seated inside the barrel adjuster long-term may cause some sort of damage and/or failure.
I think my best option may be to simply remove the barrel adjuster so it doesn't abrade the cable over time. Is there any danger/drawback to doing so? (As far I am aware, the main role of the barrel adjuster is just to fine-tune the tightness of the brake without tools being involved. I can live without this convenience.)
