AZSCTACO, that is ok if it works for you but you are not changing all the brake fluid that way. The fluid in all the lines and calipers is still old and as time goes by will mix with the new.
That would be like only changing coolant by a drain and refill of radiator or changing oil by draining pan but keeping the old filter.
Again, whatever works for you but out with the old and in with the new is not taking place that way.
I don't know why but what comes to mind is your new wife is divorced but her other husband still lives with her in the same house. Man that is weird.
