To create a strong password-remember-record-record again and record it)
Best way to use brain wallets? Create your own language, just like how Tolkien created his own language for the elves. With your own language, it would be very hard to brute force as this would not exist in any dictionaries or any documents online or written in books.
Brain wallets are something a good idea. This is the most trustable wallets to use.
What do you mean with "most trustable wallets" to use?
With brainwallet OP referes to wallets generated from a password which will be stored in your brain.
So 1) there is noone you would have to "trust" as a 'walletprovider'. And 2) There are far better options for a wallet.
With normal passwords you are cutting the search space for the priv key to ~1/20 compared with some RNG (considering enough entropy).

yes brain wallet are useful nut also has disadvantages when accidentally damage so it cant be able to use or log in

1.Only you know the mnemonic in your brain, so you just need to trust your memory. (this is the hard part, unless you have a good memory)

Even if you have a brilliant memory it is not that easy to memorize a mnemonic seed of 24 words or an even longer seed.
However, even if that is no problem for you the risk is simply too big.
If after a few years you only remember 22/24 words, it is still nearly impossible with current computation power to
bruteforce the missing 2 words of your seed.
This problem is intensified by the fact that your memory may be impaired by a medical event like a stroke, a medical
event caused by a accident or even the onset of a medical condition like dementia or Alzheimer´s.
All in all I would recommend a brain wallet only for an amount of Bitcoin that you are willing to lose.
As i research for its advantage and disadvatages to contribute to this thread, i just found this article. Credit to the owner. I just add my own idea about it.
Advantages:
1.Only you know the mnemonic in your brain, so you just need to trust your memory. (this is the hard part, unless you have a good memory)
2.There is no written record or possibility of an online hack. (hackers cant find it, its in your brain)
3.Your brain wallet is always safe from hacking. (i think its is same as number 2?)
Disadvantages
1.If you suffer from any medical condition like amnesia or dementia, you will lose your coin keys with you. (yes, if you this kind of problem, brain Wallet doesnt suits you)
2.As there is no written backup, if you forget your mnemonic phrase, then your funds are lost forever. (Thats your major problem, you cant crack your password)
3. If someone knows you have a lot of money in your paper wallet, they can steal that. But if someone gets to know that you have a lot of money in your brain wallet, you can get kidnapped.
(this the best, funny but true).

Doesn`t look very safe to me 
very bad, we are humans we have tendency to forget, keep it simple, write on a piece of paper.
What about if a disease occurs to you and you can't remember it? You'll lose the wallet!
Not a good idea!

I thought the same thing as you did. For example, if a bitcoin's owner is suddenly being diagnosed with Alzheimer or Dementia - it's a huge possibility that he/she will lose the memory of many things, including the password for brain wallet!
Alzheimer or Dementia are usually of a slow onset. But bullets, strokes and meningitis strike fast and produce the same effect.
Of all the things that might disappear in this world one thing is guaranteed - your brain will vanish.
brain wallets are always bad.,
because our mind always chooses easier option becuase it has to keep it in memory i.e. in our brain.
that is the reason brainwallet site got closed and majority brain wallets got hacked and funds sweeped.
if you still want to use brain wallets then use some salt to make it more difficult to crack or guess., e.g. warpwallets are doing the same.,
they even have open challenge to break their wallets .,

For me it sounds like a terrible idea.. It surely can be safe, but I would every day think "what if someone think of the same as me" 
I would be super paranoid at least..

brain wallet is not to easy how if we have a lot of same thing and easily forgot
Bad idea for sure, you can easily forgot your mem phrase or get hacked if its too simple, no way to prefer a paper wallet instead of a brain wallet

To be honest, this sounds like a fast way to loose money.
+ the burden of remembering it will most likely make you forget it
how many people here alway have a hard time remembering there ccv ?
except if the phrase is stupid simple to remember
i wouldnt advice storing your entire cash on your brain
by the way , your brain is digital !!!
print a paper wallet

yes brain wallet are good because of the brain of people are very weak they con not remember our password so they help from the brain wallet to get purchase money
Brain wallet is the good technique that man can do with his brain power. Bear in mind that human brain is a complex thing and as many algorithms, you think of and provide them with your passcodes or something else at any moment something can happen to you. In that moment it is 50 percent that you will forget your passes and that was your only storage you've stored it. Afcorsee the human brain is exceptional but always make a backup.
brain wallets are fine - don't believe the charlatans, they don't know what they talk about
just mind your password - make it long enough and impossible to guess.
That's all good, a long strong password will make the wallet secure, I don't think anyone is arguing that point. But as people have pointed out what if somehow you forgot that password, making it long and strong just makes it easier to forget, but even if your memory is somehow exceptional what if an injury or disease makes you forget it? Then what? just mind your password - make it long enough and impossible to guess.
then you ought to write it down, preferably not as is, but rather as a puzzle that only you can solve.
I'd also advise to somehow hide the hint message among some unrelated data, so even if someone sees it he wont have a clue that this is the hint to your brain wallet.
for that reason, I would not keep it in a safe.

My thoughts about that. What if you are loosing your mind the past view years? You get something on your head in an accident and lose parts of your memory?
