Well I'm home, so I'm back at it.

Ran to the hardware store and picked up four M12x1.75x40mm length bolts to go from the bracket to the caliper. I think this length will be good. Here's how many threads are stick out, with a lockwasher uncompressed, with 6 threads sticking out of it. Once it compresses I expect I'll get another thread out of it. I figure 7 threads should be good. But if I were to do it again, I'd probably use 45mm length.

So IMO, ideal length for the Bracket bolts is 30mm, and ideal length for caliper bolts is 45mm. I'm no mechanical engineer, just my mechanical judgement there...
