Trust me, I just went through it.
This is exactly why I want the software for that just in case moment if I make a mistake or just plain ole do a stupid.

Get the upgraded version with the aluminum cap and make sure to flush the power bleeder and lines with denatured alcohol before storage. Forgot to do that one year and had the line explode on me under pressure. Not fun cleaning brake fluid all over the engine bay. Lol.
Oh man!! Thanks for letting me know. If there is one thing I don't want is brake fluid exploding. Stuff will strip paint like toilet paper. I should have gotten the aluminium adapter version but that wouldn't have arrived in time. I think I can buy it separately in the future.
