Brake Fluid

[R_CK_R]

hey guys
maybe as some of you know, I have a little problem with my master cylinder...
yesterday i got the repair kit (it only took 12 days from USA to Germany [cl )
In the shop manual is written: "the supply tank should be filled with genuine G.M. brake fluid No.9 or No.11"

now my question: what the heck is GM Brake Fluid No.9 or No.11???
And where can I buy this brake fluid?

I´m pretty sure you guys can help me out

everything I read says DOT 3 or 4 is fine to replace 9 or 11

thats also what i found out so far...

i think i´m gonna replace it with a DOT 3 brake fluid.

Thanks
