I get the feeling you haven't stuck a 1" sheet metal square into a brake diagonally.

And then you'd have one half of a Caltrop that would require a jig to weld to the other half.

I use a brake every day. I fail to see a problem forming a 1" square diagonally. I do much more difficult things on a daily basis. However. if the purpose is to puncture tires I would use a bigger square. The only way they will be very effective is if they have a flat side down. The sin of a 45 degree angle with a 1" side would give .707", which would be just over 5/8" max to puncture with 16ga metal. I would think you would want at least a 1" tall point which would require a 1.5" square, minimum.

Forget the 1".

Grab a piece of paper, fold it into a square. Fold the square diagonally at 90 degrees. The result is nothing like a caltrop.

You get one triangle at 90 degrees from another triangle. It's an unstable thing that will roll over if a tire runs over it. It could land with the single point facing any direction, but not straight up. If it lands with a point facing straight up, the tire will crush it flat.

(edit---I could not see any of the three posts above when I made this post).
