    I have to disagree with that. Brake fluids in all but some special systems
    (perhaps VW/Audi) are a glycol/alcohol based material. Mineral oil (such as ATF,
    Dexron or hydraulic fluid) may be used in these special systems but will quickly
    destroy the seals in any other braking system. If you get mineral oil in any form
    in your braking system you will be replacing the whole system, cylinders, lines
    and all.
