Wonky Fork Drilling on Moto Grand Record
 
After first ride's review, there seems to be a lot of tweaking needed. Should I add this skewed brake drilling to the list of fixes? Would it hold to just drill the back hole a teeny bit to allow the bolt a straight path, then widen the front hole to compensate?

If I leave it be, the pads will just wear-in to the rim, but will I be losing stopping power? Is it just an aesthetic and mildly compulsive issue?

That's the sort of thing I'd fix just because it would drive me crazy every time I looked at it.

I'd drill it so the brake will sit straight. Then, if the holes seem sloppy, you could pack them with JB Weld front and back with a plastic coffee stirrer or something similar running through them for a pilot hole. When the epoxy sets up, pull the stirrer and re-drill.

Proper fix would be to weld the holes shut and re-drill, but I suspect that is not an option because most of us do not have the skill or tools to do so and damaging the fork finish will add to the problem of getting it fixed totally......Uhmmmm.......I'd just try to find a replacement fork, hopefully from the same model bike or very similar.

Just had a thought,.......... if the rear nut on the brake bolt is not recessed, maybe drilling the hole bigger towards the correct direction will make things realign, but with a recessed brake nut instead?? It will not work if the problem is with the front hole or both holes though.

Chombi.

Bend the bolt. ;)

Leave it, I bet the front brake does not squeal when braking force applied. I have two French bikes with the same basic situation. It is part of the "charm".

Dispatch the crude alloy spacer behind the brake though, find a smaller Campagnolo style part, looks too Weinmann.
