replacement Campagnolo brake bolt?

I noticed recently that my front brake pads were wearing very unevenly. (I don't know the exact year or model but it is Campagnolo that I believe dates from the late 80s.)
Dismantling the brakes, it appears that the pin that holds it all together is bent. (I suspect this happened when the bike was stolen and wrenched out of a small car.)

I've tried straightening it, but that didn't work 100%

Does anyone have a replacement lying around or can suggest where I might find one?

here are some photos.

many thanks

If that's bent, it's not much bent.
but I've had the issue before, with Shimano 105 caliper brakes from the late 1980's, where the bolt down the middle ended up bent. My local shop had an extra sitting around. But such pieces are rare, and I imagine they're more rare with Campy.

It's probably less trouble (and perhaps less cost) to just replace the front brake. If you're really wedded to Campy, I have a Veloce (dual-pivot) front brake I could sell you.
If you're really wedded to this exact brake, well... good luck.

It's unlikely that the pivot bolt is bent, and also that a bent pivot bolt would cause uneven pad wear. Can you show a picture of the pads so we can see the wear? I suspect either the calipers weren't centered properly or the arms were bent at some point (perhaps to reduce squeal).

Thanks John,

I'll snap a picture of the pads and calipers this weekend and put them up for examination.
I appreciate the help.

There is a LOT of things that can cause that.

How the brake is seated on the fork crown area (whether this is perpendicular to the wheel) or if it's uneven etc. Whether or not the brake arms themselves are straight or if they've been bent to provide toe in. I'm with post #3 that you can't assume the pivot bolt is bent.

At this point i'd just try to first reset the brake mount on the fork and see if the pads hit straight (will be hard to tell with your worn pads). If not then try bending the brake arms themselves with a crescent wrench or appropriate park tool.

Check Ochsner for Campagnolo part and components:

http://www.ochsnerusa-store.com/index.php

Ochsner only recently started selling to the public. They were exclusively for store-front bike shops. So they are getting used to dealing with the public. So their website isn't the best. But usable.

Is this what you need?

Looks to me like you just have to set the toe-in properly.
