It’s caused by the brake torque deflecting the front spring, combined with the somewhat flexible radius arm mounts. This allows the top of the axle to move forwards under braking, this pulls on the steering arm, and the result is a left pull. Well, that’s the easiest way I can describe it. To fix it, you need to fit a simple strut, each side between the top of the axle, close to the king pin eye (or even to an extended king pin) and a point halfway to the rear of the radius arm. I don’t have a picture to hand, but this has been talked of before in this forum. A search should find it.
