I think the point of an approach brief is that it is just that...brief. If you have a co-pilot, they can go into more detail if required, or talk you through the whole approach. In just over 2000 hours of military flying (granted, most of it single pilot), I have narrowed it down to:
Date of the plate
Sector entry and any initial height restrictions (if required)
Approach commencement height
Intermediate step heights
Directions of any turns for reversal procedures
Minima
Mapp procedure
Orientation of the runway / environment at minima
Actions on aid / comms (and perhaps engine) failure
Other pertinent info like circling restrictions should be verbalised as well.
Extraneous nonsense should be left out as this takes up time, will be difficult to verbalise due to radio traffic, and is also prone to confusing the essence of the approach.
Hope this helps.
