Both of you
Both you
Both of the brothers
both the brothers

the both brothers

'Both you' is not acceptable as a free-standing noun phrase, but it is a possible collocation in contexts such as 'both you and your friends are always welcome'.

'Both you' is not acceptable as a free-standing noun phrase

I agree with Bobk,but you can say for example :
"you both want to drive that car" (not both you)

Additionally,

These are the same. 'of' has been omitted:
Both of the brothers
Both the brothers

The difference between these is specificity.
Both the brothers <predviuosly mentioned or about to be defined>
Both brothers

The second one below is odd (). Both means two.
Both of you <'you' is plural, as in you two>
Both you and Sam

This one is not possible. A pronoun cannot be modified by a determiner, but a noun phrase can be; e.g., The both of us:
the both brothers <ungrammatical>
the brothers both <grammatical; used for emphasis>

The word both has three functions:
1.Adjective: I want both cookies.
2. Conjunction: I am both tired and lazy.
3. Pronoun: Both of us

All the best.
