They don't actually rotate *around* the thrust bearings; they rotate *between* them. I agree that it's a cool feature.
I've had my XTR brakes for over 20 years, and they have never squeaked.
They worked well with the STI shifters I had the bike built with. There were "Travel Agents" in the brake lines to adapt the long-pull brakes to the short-pull levers.
When I recently changed the bike over to trekking bars, I was able to use long-pull levers (Paul "Love Levers"). When I took the bike out for a long shake-down ride, I found that the brakes worked markedly better than previously. They felt like disc brakes. Also they did not squeak!
