This is worth doing. Everyone seems to forget the hydraulics associated with ABS. A real flush involves cycling the ABS hardware as well- a failure there is $$$$$$$. Moisture content is only 1 facet of brake fluid. It also absorbs other contaminants. It can be dis-colored and still be fine from a water content standpoint.

IMO worth the money.

Most club track events require docs that show a change within 24 months. I'm thinking there's a reason.
