I'd like to set up the Tektro RL570 as stand-alone brake levers. I believe this is possible (?). I've set them up 'normally' and they kind of work, but in a way that's different from what I'm used to. When I apply the lever, there seems to be an excessive amount of cable housing movement. Is this to be expected, given the original (inline) function of these levers, or am I missing something in the set-up? Any help would be appreciated.
