Is this new?

The bearing brake? No. But I'm not a fan of the concept though. It defeats the point of the bearing by making it drag along the surface rather than rolling. I also don't like the idea that the bearing is working  every second that the motor is running. Those tiny bearings are notoriously hard to lubricate, so this can be problematic. The best way with shielded bearings is soaking. Sealed bearings are nearly impossible to lubricate, so their life span is limited.

Same here.  I'm not a pro, but I've never had a bearing not work just fine as-is.  I don't know what problem this brake is supposed to be solving.

I do remember Pat Warner commenting about taking the bearings off, and using a fence when possible to make the bearings last longer.  If I did enough work to wear out the bearings, I'd get on board with that.  But this brake is the opposite of that, like crazy guy said.

Brake? Like a one-way bearing?

If bearing drags the brake is not setup correctly. It should be tight enough to prevent free spinning, but loose enough to allow rolling along the reference surface.

svar, I have never seen one work exactly as intended for more than a minute or two.
I have used  a Cantek router with a similar set-up and it just doesn't work in practical application. All it takes is a little bit of adhesive getting flung around as you trim, and it gums up the works.
