brake fluid quantity required for flush, and brand experience

I can't find any spec (even RTFOM) or insight in posts here about how much brake fluid to purchase for a proper flush. Any help from those who DIY previously?
Further, I see that BEVO lists only the MB branded product as approved, as if MB makes the sh*t. Rock Auto only offers Pentosin, but of course I can buy MB fluid elsewhere and likely shall as a safe default. Any thoughts on brand?

I saw your post on the ML sub. I am able to flush my 2013 ML350 with one bottle from the dealer. Not sure on how much one bottle is, 1 Liter I believe.

Edit: I think the bottles are only $20. The 1 bottle is just enough to flush my system, so my advice would be to go ahead and buy 2, just to be safe.

Thank you, yes each is 1 L and I'll get two. $15 from an eBay vendor, I saw.
