What's the weight on that assembly as shown? And how much force can the brake withstand until it goes down?

Re: pic: Arm Brake
Alright, Firebirds, you've really got me interested this time. (Mostly because we're facing a similar issue come Palmetto, but also because y'all are just plain good folks.)

Now, I can figure out that the cam rotates onto the lever, engaging the brake and giving it a good degree of torque, given the length of the lever--but how does it hold its position? Friction? The keyway? That fairy dust that Tytus Gerrish keeps referring to in his designs?
