Thanks for the video David. Excellent discussion. I'm not sure I buy into the idea of pulling the bleeder hose off before tightening the fitting - that doesn't make sense. As you said, that is a sure fire way of allowing air back into the system. I would need to hear the science behind the other vlogger's methodology. Did the car drive well when you were finished? Any sponginess in the pedal? Please let us know as I am about to attempt the same on my 2018 Rav4 also.

I felt the same way as you and I've been working on brakes for years. This channel called Car Care Nut has shop and all he works on is Toyota and Lexus. He is very meticulous and trustworthy. Look at the 17:30 mark. kzread.info/dash/bejne/nKSdurF7gs7Ao5c.html Thanks

The pedal is not spongy, it's quite hard.

I notice that there is a line of air bubbles running through brake fluid as you bleed it out. Is that air from the brake line?

There wasn't any air in the system initially since the lines were not broken open, I was just flushing the system. I think the air bubbles were from an imperfect seal on my vacuum pump. The pump was probably sucking in air from the connection. There was not any problem because the air was going into my hose and not into the brake system.

Will a 12-oz bottle of fluid be enough?

For a complete flush you need at least one quart to make sure you get all the old brake fluid out.
