The cable of my front brake keeps breaking at the same point. I’ve changed the cable multiple times and after a few long rides it breaks at the exact same position. The cable cuts at the point where it’s attached to the caliper.
Sorry for the bad english.

You are over tightening it.
First thing I would do is make sure there are no sharp edges on the cable clamp where the cable keeps breaking. It is also possible to crush the cable too hard, check the torque specifications and make sure that the cable is placed in the correct location.
You aren’t routing it right. It should be in the groove on the other side of the bolt. And you are probably over tightening it. Put the part number into si.shimano.com and look at the torque specs for it.
While it’s true that the cable should be in the groove of the pinch bolt and you may be overtightening it, in my experience those particular brakes always eat cables. It’s not just you. Pretty much the only time I’ve seen one come through the shop with a fully intact cable was when the customer had recently had it replaced.
So the answer: probably nothing. Maybe try an avid bb5 or bb7.
This question has been asked before in this sub. Check this out:

Is the brake lever activated or is this in its ‘relaxed’ state. If it’s not actively being pulled then the brake caliper/pads need to be adjusted.
All the stuff about cable routing is correct.
I would also mention. If you are able to press the lever so far that the bolt that holds the cable goes bephnd 90 degrees. It will also damage the cable in this way.
My English is not great enough to explain it in a way that is easy to understand. Sorry for that. If someone can help me out by explaining it in plain English, I would be greatfull.
