I, like many here, use a syphon to refresh / replace my power steering fluid. I got to thinking (which can sometimes lead to strange ideas) why can't I do the same with the brake fluid? Syphon from the reservoir and replace with OEM brake fluid? Of course, you can't empty every drop from the reservoir lest you make an air bubble in the line. But you can do 90% of the reservoir and top off to the 'full' mark with fresh fluid every week or so until the reservoir has nice, clear fluid again.
Have I gone mad or will this work?
