Brake Fluid Change - Vacuum vs Invalid Mode

Should be able to get away with either, as long as you're really just doing fluid replacement, there is no air in the system now, and you make absolutely sure never to take your eyes off the reservoir and let it low enough to slurp any air in.

It can be prudent to at least have a scan tool on hand that is able to kick off the actuator bleed sequence, just in case a mistake happens and any air gets in.

 

I've used invalid mode, without vaccum assist, and otherwise followed the nuts about bolts video, apart from the order: repair manual says to "start with right/front, and go around counterclockwise". I'm paraphrasing, it takes them four verbose paragraphs to say that, but that's the gist. More info in a link in my signature (on a phone turn it landscape to see signatures).

 

Third method, like the vacuum method, except the brake reservoir is pressurized. Often with a reservoir attached with fresh brake fluid, ensuring that the reservoir doesn't run out of fluid.

SM-G781V ?

 

When is it recommended to change brake fluid? I just reviewed the official maintenance schedule for a 2017 and I must have missed that - don't see it anywhere.

 

Toyota USA says nothing about brake fluid change. Toyota Canada I believe followed suit (note past tense) but at least as of 2014 (when I happened to notice) says every 48k kms (30k miles) or 3 years, whichever comes first.

BTW: at least for that year the CDN schedule was in an easy-to-read table format. Not sure how long that lasted; currently it’s gone from the booklet, completely: only option is online, enter your car and miles.

 

I too would like to flush my brake fluid on my 2016 V.
But I read so many concerns/ failures of DIY without a TechStream or like service computer.

I would do the typically (old school) two-person procedure: pump pedal, open caliper nipple, close nipple, release pedal, and repeat.

What are the odds of success?

Ive done our ‘10’s twice, non/Techstream method, no hitches. See post 3.
