Me and my brother used to have BTC on bitcoin core, and we encrypted it.
But last year the device that we used for that specific wallet and also the notes of password were on my room, but the house got caught on fire and unfortunately everything was burnt down.
But last week i opened my hard drive to put my wedding pics on it, ive found the backup of wallet.dat on it, but we have no idea how the password could be.

I have the wallet.dat only the password is missing.

Both of you must do the best to remember pattern, length or other characteristic of the password. Have you checked these options?
1. Possibility that one or both of you also made backup of the password or note of the password.
2. Possibility of re-using password or password characteristic that being used elsewhere.
3. Whether you use password generation software.
4. Whether your hard drive contain the password or note of the password.

Bitcoin Core use strong encryption, which makes it's impossible to perform naive brute-force your wallet.dat file unless you used weak or short password.

This sounds like your wallet encryption password was stored in a file on the storage device for your Bitcoin Core wallet. If you made backups of the wallet file, then why didn't you make backups of the password file? This seems not very logical to me.

Who created the wallet encryption password? Was it human generated or some random password? Humans tend to have certain recipes how they "invent" their passwords or they re-use common passwords they had and make only little adjustments.

Knowing the details about possible password usage may help a lot to crack such an unkown password, but you need to have at least some ideas about what could've been part of your to be cracked password.

You must have some idea of what your password looked like for the bruteforcing to be successful. Otherwise, it's never going to work unless your password is something incredibly simple, which I don't think it is. Losing everything in a fire seems horrible, but you can always learn something even from negative experiences. In this case, the lesson is not to keep your passwords, seeds, keys, etc. saved digitally. Instead, use laminated paper or metal backups. Also, make multiple backups in different geographical locations. If an accident happens in location#1, you can still recover your coins from location#2, #3, etc.

Since it's allegedly your backup, you should at least know a couple of possible passwords or parts of it for bruteforce method to be viable, yes?
If so, try BTCRecover and construct a "token file" based from the possible password parts that you can remember.

If you need assistance on it, you must describe it in detail without being specific on the password itself,
like for example: 8 to 10 characters, first 7 letters could be word1, word2 or word3, followed by numbers then a symbol.
Since it's a backup, if you've changed the password after that backup is created, you should refer to your old password.

If you prefer DYOR, here's its documentation: https://btcrecover.readthedocs.io/en/latest/

Otherwise, there's no way to retrieve your bitcoins since your private keys aren't saved anywhere but your wallet.dat file and its backup.

I'm not sure there's anything that can be done to help you here mate.. you need the password+ the wallet.dat file to access your funds since the wallet was encrypted. the password was lost in the fire, I don't think there's anyway you can recover your wallet.. did you buy any chance save your seed phrase somewhere else or on your hard drive?
