How much brake fluid?
I did a few searches, and didn't find an answer to this question. Also checked the RX-8 manual and didn't see an actual number. I am planning to replace my brake rotors and pads, and will flush, not just bleed, the brake fluid at the same time (I am switching to ATE Super Blue). How much brake fluid am I going to need? I want to make sure I have enough, but at $10 a liter, I don't want to buy too much either. Thanks.

You'll use maybe 2/3rds of a liter. I like to switch between Super Blue and Typ 200. They're identical except for color which makes it easier to tell when new fluid has reached the caliper.

I switched to Super Blue 2 weeks ago. You will need only a one liter can. I didn't know what I was doing and wasted a bunch of brake fluid and still had some left in the can. About 2/3 of a can sounds about right to flush the whole system.
It looks like I put windshield washer fluid in my master cylinder
PUR NRG - how often do you bleed your brakes? How often do you replace all the fluid?

General rule of thumb is you want to flush at least once a year. Since brake fluid absorbs water I like to do it right after the rainy season.
The only reason to bleed brakes is if there's air in the lines or it boiled during a track event. Once a can is opened the fluid starts to absorb moisture--even tightly closed you should throw the can away after three months. Because of that if I ever need to bleed the brakes, I'll do a complete flush. Better to have new fluid in the car than throw it away in the can three months later.

Boiling brake fluid usually occurs only on the track. You'll know because the brake pedal response feels spongy/mushy and the car isn't braking as quickly. Go easy on the brakes for the next lap and it should feel much better, but still not as good as before.
