I have a road BB5 disc brake as a front brake with Campagnolo Xenon levers. I can't lock the front brake up and it doesn't seem to stop well enough.
It engages as soon as I apply force to the lever so I know that the pads are well aligned. However I can pull the lever all the way to the bar without it locking up, and with seemingly no extra stopping power after a certain point.
Do you think that it could be because I used a cheap brake cable, and it is stretching when I apply force?
What can I do to remedy this?
