Let's say you have a 208 or 241 T-case with a rear slip yoke and a rear disc conversion without parking brake levers. Transfer-case mounted brakes are a neat idea, but you can't use them with a slip yoke. How about mounting it to the front output yoke? Then when you park, you set the brake and then pull the shifter to 4H (or Hi Lock if you have a slip-yoke 203). If you are full-time or have the hubs locked, this gives you braking with all four wheels.
The drawback is that you rely on the chain to hold the vehicle in place. Fortunately, it has the gear reduction of the differential on it's side. If you break something in the rear driveline you still have the front driveline holding if the hubs are locked. This is the same situation as a rear ouput mounted brake.
I do have another question about driveline brakes in general. They seem safest with a spool. Isn't is possible that if you parked with almost no traction under one rear wheel that it could spin backwards while the vehicle rolls forward? Would a Detroit allow the same thing? The differential is actually driving the axles backwards since the driveline is resisting the forward movement, so a backwards spinning wheel is overunning the differential and keeping it unlocked?
