How much Brake Fluid?

Until I'm ready to solo it, I'm having the dealer flush my brake fluid. The motorcraft boss supplement doesn't say exactly how much fluid is required to do this. So how many bottles should I bring?

2, better to have a little extra. Plus fluid is cheap.

Ok, thanks.

PS. I use Motul RBF600. $20 a bottle, btw!
I used 2/3 bottle of ATE flushing the clutch, as you only get a little out each time you swap fluid by pumping. For a flush, I like to run a little more through than necessary and an extra $20 isn't much considering how much it costs to maintain this car. My track car I just bleed it all the time so I only use 1/4 bottle or so each time, and over the course of a year it gets equivalent of a couple flushes.
