I had made a brainwallet which i thought noone could have guessed and never put my private-key somewhere.

Sorry, there is nothing you can do.
The mistake you made was thinking that nobody would or could guess your password. No brain wallet is safe. There are 6 billion people in the world. What are the chances of one of them using the same password? What are the chances your password being guessed by any of the thousands of computers that are making millions of guesses every second? Both of those possibilities are very high. Any password that can be memorized can be guessed easily or accidentally.

... The 12 word mnemonics that have 128 bits of entropy generated by Electrum and others can be memorized, and so can be used as brainwallets...

There are people that would have no problems memorizing 12 random words. Heck, there are a few people in the world that can memorize thousands of digits of pi.

But, don't expect most people to be able to do that.

OK fine, but I just want to point out that you kind of stress me out a little when you say "any brainwallet you can memorize can be cracked" because it makes me doubt my understanding of cryptography (because it implies that the 12 word randomly generated mnemonics in wide use are not strong enough).
