2010 K13GT, 44k, have had the front shock out twice. Once for replacement, once for follow-up adjustment. I did not drain the brakes and cannot find that step listed in my factory service DVD as part of the shock removal. So long as the calipers are removed and properly suspended out of the way and avoiding kinking, and the brake lines are unbolted from the fork arms and frame, I see no need to open the brake system.
My ball joints were fine so left them undisturbed. You only need to pull the large pivot bolt for the lower suspension arm and work it down far enough to be able to slip out the shock. Note that there are some one-time use bolts (per BMW) that are pre-treated with thread locker.
BTW-- you only need the engine lifter if removing both shocks at the same time. Front or rear can be removed individually with bike on center stand and opposite end of bike strapped down on the lift.
