I have two sets of extractors that I hardly ever use. When they snap they turn a nightmare situation into an impossible one!

Extractors do work. I'd say I've had about as much success as failure as long as you can get a good centre dot and a good hss drill you can use them. Generally some applied heat makes them better.

My method would have been Dremel through the spacer then heat and mole grips.

If not I have three spare hubs.

Just drill the head off the bolt, dead easy with a hex cap. Then take the stub out with mole grips when the caliper is out of the way.

I'm pretty sure this is what I did in the end!

I think I remember that the bolt was either slightly bent or very corroded within the caliper.

Very good advice,
Sometimes the most logical solutions are overlooked!

Before drilling it off, try hammering in a torx bit into the Allen head. I found this worked a treat and saved a bit of messing around.
