The actual bolt goes through the forks but screw bit is too wide to tighten it.
Not too sure about drilling it! haha..
Ok, so when you look at the brake, there is a length of threaded rod that comes out of the back of the brake, this fits into the hole on the front of the fork.
There is a cylindrical nut that goes into the hole on the back of the fork, and screws down over the top of the threaded rod, holding the brake onto the forks.
Your problem is that the cylindrical nut will not fit into the hole on the back of the forks? Or something else?
