I wanted to be sure that it wasn't going to loosen. In hindsight, I think I would give it a go without the loctite. When I first put the nut and brake on, I had to back the brake off a little to get the ports pointed up. When I then tightened the nut, it was tight but you were still with relative ease able to back the brake off more than I liked which had me thinking it would eventually loosen. Now, I think you would need to really go to town with a wrench to get it off. Not necessarily a bad thing I guess!
