It doesn't have any visible effect on unrusted metal so you should be OK with the bores and bearings. For the hydrogen embrittlement I've looked a lot on the net and the only place where people have concerns is when de-rusting springs. If you are worried then there are suggestions the baking in an oven for some time (can't remember how long) reverses the effect. I can't see how a day long treatment on a large lump of cast iron like a caliper is going to make any difference at all.

My personal opinion is it's the nearest thing to magic I've seen in a long time. You can see from the attached pictures the change to heavily rusted metal

One thing you do have to watch out for is that anything you treat then starts rusting again at an amazing rate - there's a fine coat of rust within days so it is best to give parts a quick coat of paint straight away.
