Hi,
Thanks for the replies its actually the side facing away from the seat tube, it probably needs a millimeter take away roughly, the hole at the back is actually wide enough to take the bolt but probably not the recessed nut, I'm going to get a set of brakes with just a hex bolt so hopefully it should be wide enough. it also has a lip kind of around it giving it a bit of extra strength.
I think I'll probably give it a go progressively after I order the brakes.
Thanks everyone.
