Bind brake to half axis?

I'd like to bind wheel brakes to the toggle rudder on the Thrustmaster 16000 HOTAS Throttle.

The rudder paddle on this device tilts left or right. I'd like to bind the left tilt to simultaneously brake both left and right wheels with analog effect.

The problem is, squeezing the rudder left or right binds the entire axis, which returns 0.5 at rest, 1.0 to left and 0.0 to right.

This means the the device is applying 50% break in rest position, making it unusable.

I have not touched the Thrustmaster Target software and would prefer to remain that way.

Is there a workaround to make use of this axis?

Thanks! That worked.

Happy my first guess that the cross hair icon meant calibrate. Didn't want to delete all my controls. Tooltips and focus / pointer over highlights would be a wonderful addition to the UI. That menu page does not have a ? help icon.
