    I have an '07 DC V6 with almost 60K on it, and want to flush my old brake fluid. Which break fluid have you used and found satisfactory?

    Before I get the usual "use the search feature" I did do that, and did not find any recommendations.

    Use the brake fluid type recommended in the manual or on the lid of the master cylinder reservoir...use only that, none other. I'm not sure what it is (DOT3, DOT4) but use nothing else or you'll die.

    Seriously.

    Not joking.

    Well, maybe a little. But still use only the same type.

    The lid says DOT3 IIRC. I put in DOT4. I'm still alive.

    If I recall correctly dot 4 is the same as dot3 but has a higher boiling point. Dot 5 is completely different and you will destroy your brake system using it in a system that takes dot3 or 4.

    I've been using this stuff for the last 20k miles, so far so good. DOT 4 can be used in DOT 3 systems. Like someone else said DOT 5 should not be used unless you really want problems.

    Correct! DOT5 is silicon based and is not compatible with anything but DOT5 specific brake systems. The advantage is DOT5 is not hygroscopic. The most common use I've come across is in older HD motorcycles.

    DOT 5.1 is compatible with DOT3/4 and has a higher boiling point than either. It usually marketed as a race spec/quality fluid.

    ATE blue?? funny.

    i use it in my track car. hated it. first it dyes everything blue. the reservoir plastic will be blue. second ATE is a great track fluid..from what i understand, it isnt a long term brake fluid. it resist heat better than regular stuff, but what it gives up to do it..is it's resistance to absorbing water..i use MOTUL 600 now in the track car, it is clear. but like the blue stuff (or gold ATE) i change it out every other track day.

    for my tacoma, i'll use some quality stuff from toyota..it is designed to stay for a long time.

    That's interesting. Some old posts said it was great stuff and a good way to tell when you have your old fluid out. I'll try and locate the old post if I have time.
