    ATE super blue (or the amber version) Good fluid that a bunch of us use and with the two colors it makes flushing a bit easier.

    others run Motul

    I flushed my brake system after 2.5 years on the factory fluid. "ATE Super Blue" and "TYP 200" are awesome brake fluids(interchangeable blue and clear color for a complete flush indication). They provide high boiling point and great solid brake feel.

    BTW one thing I learned is the factory bleed isn't good at all. My brake lines were still full of air bubbles from the factory. Look into purchasing "Motive Power Bleeder" if you have some extra cash. It makes brake system flush breeze and pretty much guarantee a perfect bleed.

    FYI DOT3 and DOT4 fluids are compatible. So no need to change anything in the brake system.

    DOT 5 is the only one not compatible. I don;t remember why you cn't use it, or wat needs to be changed if you want to use it though.
    But just remember which on you're using. you're not supposed to mix fluids...DOT 3 with DOT 4.

    Just remember that brake fluid is one of the best paint strippers there is. Wear nitrile gloves and be very careful not to spill it onto anything. Bleed the calipers into a bucket through some small diameter silicon tube. Don't let it piss out on its own.

    I believe most race cars use Dot 5 or 5.1. Check your owners manual on your car. You might have to convert brake parts to be compatible with that grade of brake fluid.
