I noticed that one of my front brake pads was dragging lightly on the rim the other day. I've never noticed it before.

I took a couple photos - I pumped the front brake a few times and you can see the right pad is lightly up against the rim but there's quite a bit of room for the left pad. I thought I could adjust the spring tension (3rd photo) but there's nothing to adjust, the spring appears to float freely in the brake frame.



In the second picture, you can barely see the top of a hex bolt that can be used to center the brake on the rim (Red/Force) and I fiddled with that for a bit - turning it one way appears to actually close the brake arms, and turning it the other seems to loosen up the rotation of the brake frame so that the right pad isn't dragging. Not really though, I just checked again.

Lastly, I'm theorizing that the cable housing might be a skosh long because the housing is pushing down a little on the brake, although turning the bars in either direction doesn't appear to affect anything. I could presumably clamp the brake a bit higher on the cable or just shorten the housing a few mm... it's a jagwire housing and it's fairly stiff.

Any suggestions?
