The length of driveway you describe is not enough to overheat your brakes. As mentioned, don't use 4WD on dry pavement unless you have manual front hubs to disconnect.
Use your brakes. Keep it dead slow (even stop before starting the scary bit). Set your trailer brakes a little on the aggressive side and go manual on the trailer brakes if you think the rear end is going to get loose. Once you've done it a couple of times and get your heart rate under control you should be OK.
Just go slow, slow ,slow.
