Not sure if by 'brace' you mean brace
post or brace
wire..
If you're talking about putting a brace
post diagonally from the top of the corner to the base of the 1st line post, then I'd also recommend a brace wire going the other way...connecting the bottom of the corner to the top of the 1st line post.
If you're talking brace
wire in an H-brace, where there's a horizontal brace post between the corner and 1st line post..run the wire the same way as described above. Bottom of corner to top of 1st line post. That way, if the corner tries to lean, the force is transferred through the horizontal post to the 1st line post, attempting to lean it over as well.. With the wire connected from the top of the 1st line post to the bottom of the corner, it tries to pull on the bottom of the corner as the leaning force is applied.. Again, the corner is acting upon itself....literally trying to pull itself out of the ground, instead of leaning.
Another good corner brace is a 'knee brace' or a 'floating brace'.. In that one, there's a diagonal post from the top of the corner to the ground, pointing in the direction of the pulling force on the corner. A wire is run horizontally from the ground-contact end of the diagonal post back to the bottom of the corner post.. So, as the post tries to lean, it attempts to push the diagonal post...which then pulls on the bottom of the corner.
As you can see, the goal of all these braces is to transfer pulling force from the top of the corner back to the bottom of the corner.. Reason being, it's much harder to pull a post out of the ground than to lean it over...which is why these types of braces work so well.
