So I've been putting off a brake fluid flush on my 2020 OR for a while now. The main reason is that I'm confused about the process when you've got a brake booster in the mix.

At the end of the video below it goes through the process outlined by the service manual. While I have no problem trying this I've read here and on other forums that you can simply have somebody pump the brakes to build pressure, unscrew a bleeder and simply bleed the brakes that way. The service manual has some crazy steps like pumping the brakes 25 times and then repeating that FIVE times....seems wild. Is that necessary? Or am I reading these directions wrong? The way it's outlined seems like it's in steps but maybe "Step 3" in this process is all I'm looking to do?

Anyway, just looking for advice from anybody who has successfully bled their brakes on a system with the brake booster.
