Hi,
Wondering if I can ask some more advice.
Basically the bolt on the brake caliper seems to be too short for the forks. You can see the bolt just reaches to the inside of the far hole.
The forks are Reynolds 531 from the 80s. The calipers are beautiful looking Campagnolo Athena monoplanars.
Now I've done a bit of reading and it seems it's normal for the bolt to be short since the recessed nut you can see in the pic will reach through and grasp the bolt.
The problem is for this to happen the recessed nut must be able to push through the hole on the rear side of the forks but it's too big on mine. According to Sheldon with forks that expect a recessed nut bolt setup, the rear brake mounting hole should be wider than the front, on mine it isn't, they're both the same width which says to me mine might not be mean't for a recessed bolt setup but instead for something else.
So knowing nothing about brake caliper standards and their history and how they've changed over time I'm wondering what the best way forward is. I could drill out the rear hole to 8mm so the recessed bolt will go through but that's a one way thing and if I encounter issues down the line I'll have fucked up my forks since they'll be no going back.
Alternatively I could try to source a caliper that will fit but I have no idea what I'm looking for since calipers adverts never say the bolt length.
Anyone any good advice, is drilling the way to go or is this a bad idea?
Also the gap between the front of the fork and the back of the brake caliper seems really big, it's 15mm is that normal!? Or maybe there is something wrong with these calipers? confused
