Brake fluid capacity

[tuglet]

I'm planning to replace all the brake fluid in my 1997 1.8 Mk1 Eunos Roadster tomorrow. Can anyone confirm how much fresh fluid I'll need? After much Googling, the only info I could find was in the Miata.net Garage section which states 1.5L for a 1990 to 1993 car but says that this is based on "observations by owners". There is no info in Rod's manual.

Cheers
