You people crack me up!
What do you do about ATRAC trying to apply brakes to one of the rear wheels when it's locked? Or maybe it wouldn't ever try because both rear tires will always be spinning at the same rate since they are locked together.

Exactly.. you don't want A-TRAC to apply brakes to rear wheels for several reason. But the most important one is because it'll shatter your rear axle.
The locker already puts a lot of stress to it. Apply brakes and it goes kaboom.
Do you know what A-TRAC even does? why does it apply brakes? so it can fool the open diff to send torque to the wheel that has more traction than the other. If you didn't know how open diffs work. They split the torque based on the wheel taht has the least ammount of torque. A-TRAC Sort of works like a limited slip but it uses brakes/sensors instead of clutches.
So you wouldn't need A-TRAC back there because you always theoretically have 50/50 torque split. But when you lock the rear the front is a good ol' open diff and that's what you don't want. But in my opinion given this option I'd still run A-TRAC by itself most of the times. I only use the rear locker and I have no traction up front and one of the rear wheels is on the air.
Another reason why A-TRAC is better than having the rear locked is because if you haven't noticed the rear locker makes your truck swivel from side to side and not follow the exact line you want. A-TRAC goes where you point your wheels.
