replacement 80s 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

Peter

pictures

sorry about the link.

I've attached some pictures.
THough i've also been told that the bolt doesn't look bent enough to have caused problems.
I'll post a picture of the brake calipers and pads next week.

Apparently this is a very common problem on Campy brakes. I have a set of old Records that had the same thing on the front brake. I straightened it without too much fuss by putting it in a drill and tweaking it back with a set of adjustable pliers. It took some force, but the long-handled pliers allowed plenty of leverage, so no problems. By using the drill you can spin it around until it appears straight again. Just make sure you don't grab the threaded part of the bolt to do the tweaking!

In case this helps, I"ve posted more pics of the actual brake pads and shoes better showing their out of alignmentness.

If you can't get a replacement or straighten it, try rotating the bolt so that the bend id "up" or "down". You can then swivel the shoes to accommodate. just an idea!

The bolt has a slot for the spring, so it can only go one way. I like the drill straightening method. Maybe the fork hole is crooked ?

My bad, you're right, sorry! I was thinking of a GB caliper I had with the same problem. +1 on the drill & pliers then!

Do any of the campy-copy brakes use a similar bolt, maybe Dia-compe? That may be frowned on, but it may be worth looking into. I'll check some dia-compes that I have, and if they work I could send them to you for free.
