I just route the cable sleeve(jacket), making sure I turn the handle bars side to side to make sure it doesn't bind. I make sure the cable curves in a natural way. (no abrupt or sharp bends) Cut the sleeve, put the crimp ends on the sleeve, run the cable through and leave about 4-6 inches past the end of the cable sleeve. Then adjust the brake and cut off any unnecessary cable excess leaving 3-4 inches and put a cable crimp on and it's done.
