    Hello,

    I have never had my brake fluid replaced and I’m at 145k miles now. I’ve always gone based on the color but now I know that is not accurate at all.
    My main question is what should I ask for at the dealership? Like a full brake fluid flush or just a drain and fill. I don’t want them to do the most expensive thing but I also don’t want them to think I just want my master cylinder fluid replaced either.

    Brake fluid flush. That does the most good especially on your highly complex master cylinder which allows regen in a hybrid. Should not be much more than $125.

    Attached is an excerpt from the Toyota Canada 2014 Prius "Owner's Manual Supplement", which summarizes the maintenance schedule up here. The call it (sensibly) "Brake Fluid Replacement".

    Noteworthy: while Toyota USA says nothing about brake fluid replacement, Toyota Canada recommends to replace it tri-yearly or 48K kms (30K miles), whichever comes first (see attachment).

    I'll also attach Techstream and non-Techstream Repair Manual instructions, in case you're interested in the technical side.

    I've DIY'd the non-Techstream method twice. For a dealership with all the right tools, this should not take more than an hour. I used 2 pints of Toyota DOT3 fluid, which runs around $7~8 CDN apiece up through parts dept.
