It didn't break, and from what I saw on the Jeep Forum, none of theirs broke either. They stated that they "lost one". My guess, it wasn't torqued right??? I did the brakes several weeks ago, but all of that had to come off for the wheel bearings (and maybe the ball joint, too???) I did take a walk down the road, maybe it fell out at the point I hit the brakes. No luck. Still, a scary experience. I lost my brakes on my F350 years back due to a broken right front rotor (No luck with right fronts!!!)I was a young stupid teen and should have changed the rotor with the pads. I chose the wall over rear ending a car. The hole in the stone wall is still visible to this day!
If it did break, I would have needed the tow. I doubt I would have been able to extract the broken piece of the bolt out. And, that was one of the first things I did before going to HD. I stuck a screwdriver all the way through to make sure it didn't break.
