Your car uses a central hydraulic system that provides boost to
both the steering and the brake systems (notice that it doesn't have a
drum-like vacuum booster behind the brake master cylinder).
The hydraulic pump and associated components uses pentosin.
To the untrained eye the hydraulic pump looks just like a power
steering pump and its fluid reservoir is for the "power steering fluid"
(this reservoir on your car should be a tall cylindrical plastic
canister mounted on the firewall near the center, and it should
have a sticker around the cap that says "Use Audi hydraulic fluid
G 002 000" or some such).

The brake master cylinder uses normal DOT 4 brake fluid.  Don't
put pentosin in there!

If you put pentosin in the brake master cylinder, then yes, flush it all
out and fill it with brake fluid.  I hope the pentosin didn't damage
anything in the brake system...

Your car's owner's manual should have information about all this,
but perhaps you don't have one?
