If you do the rear disc on the "cheap" you lose the parking brake as you have nowhere to hook the cables on to. This is one of the downsides to "cheap" rear discs. IF you still choose to do this, you still need to figure out which caliper brackets you are going to use, "modified" front brackets, commercially made brackets, or what. This is one of the things that will dictate "how" the brakes go together.
As for the axle itself, one of the things to check is for "play" or slop in the pinion, ESPECIALLLY side/side motion, as this will help you figure out if the bearings are going out. the 8.8" seems to like to wear the gears down more than I am used to, so they tend to have quite a bit ( I feel) of looseness when you turn the pinion flange. About a sixteenth of a turn or less seems to be common ( hopefully, LESS ).The 8.8" under my Bronco blew out about a week ago because of excessive side/side play in the bearings. I got to replace the entire assembly, since it was easier than trying to rebuild the diff. This was when I found out that the blocks were broken in half. A L/S is a useful thing to have, IF it is still good. Otherwise, you get to rebuild it with new clutches/steels... This can be a PITA. The L/S is usually found in the Broncos, stock, and the F-150 that have a letter before the 2nd digit int he axle code, like H9, I3, things like that, for example. Good thing is that the CFC program junked ALOT of Fords, from what I have seen, and has replenished the supply of parts available to us, so finding a good axle should be fairly easy...
