I never put brake fluid in my Motive bleeder. I just figured it was messy
and a waste of fluid. Air pressure is enough to bleed the brakes. Of
course, you have to keep a close eye on the fluid level in reservoir.
Apparently ATE Super Blue was determined to be noncompliant with Federal
Motor Vehicle Safety Standards because of its color. For example see the
notice here: http://www.ogracing.com/ate-super-blue-brake-fluid. I had the
idea to use ATE Blue a few years ago but saw somewhere that it was illegal
in Florida because it is much more prone to absorb moisture.
