Brake Disc Bolts

[unfazed]

Aye, I should know as I sheared one of my replacements bolts a few weeks back......still not fixed it......but wouldn't dare do what you suggest is to ride with a focced up bolt

Mark it dead center with a punch. Drill it using a left hand drill bit and a variable speed drill, start slowly and do not use the full revs of the drill, to fast and your likely to break the bit.
The heat from the drilling will soften the loctite and as you are drilling it will also slowly unscrew the bolt. I would start with about a 4mm bit
