Bosch calipers; later Activa, Xantia V6, XM V6. When you uncouple the caliper fully from the carrier bracket, there is a slider that appears to be screwed into the caliper casting body. This sliding bolt or stud has an intermediate section with five flats to allow removal or installation with a specific tool.
Has anyone found a decent workaround?
My "Plan B" is to hand make a pentagonal die that can be heat treated, then brazed/pinned into a cheap podger. I've seen five point sockets advertised, but no idea if they are the correct size. They don't consistently have six flats on the driven end, either.
Removal of these sliders is necessary for my plans of caliper refurbishment, as I want to replate them in gold passivate to look new again.

No physical progress, but a note to muddy the waters:
Some people nominate pentagonal bolt sizes by length of the flats.
Some people nominate pentagonal bolt sizes by the distance from a flat across to its opposing point.
For sockets sold as brake specialty items, both types of size nomination, appear to be used.
I would have thought diameter of a circle tangent to the flats, to be the most logical determinant.
