OK, I am sure I am exposing my stupidity here BUT...I am used to installing new brake cable on my older bikes with single pivot sidepulls but for some reason I am having trouble with some new Tektro dual pivots I just stuck on a bike. Should they be adjusted differently. I used my third hand tool to clamp the brakes shut on the rim and then pulled the cable through tight and tightened the bolt. The result is that while the levers don't hit the bar they are still soft and have to be pushed pretty far before gripping. What am I doing wrong or not doing at all? I pulled the cable through with the quick release in the closed position.
