I was just wondering how to put this trick into words when I read all the way down the thread to this.
Simple and works every time.

That is pure genius! I wish I'd seen that before now.

Still don't have the little fuckers shifted. Ground the heads off the bolts yesterday with the intention of using vice grips to shift out the rest of the 'stem', but can I find my vice grips? Hoooo no. Did someone borrow them? Did the aliens living at the bottom of my garden abduct them? Have they dissolved? Who knows?

And to top it all, I bought a repair kit to spruce up the old master cylinder, to go along with the braided hoses, new discs, tarted up calipers, etc. After painstakingly stripping and cleaning the thing (taking care to note how the old components came out), I started to rebuild only to discover that the bloody rubber washer things are the wrong bloody size. I mean, did I annoy someone in my last life? Why are the gods mocking me?

Oh well, at least Ireland won the Grand Slam on Saturday.

you could try bashing a torx bit into it and see if that will grip it well enough. I've used that method to get the retaining screws off car brake discs
