With the tie rod disconected from the stearing arm, use a spring balance , 4 to 5Lbs Preload, while it is on the move. 18 to 2.3kg

I can't relate to what the 0.40mm is, mm is a measuement of lenght ,not preload energy

heres a tip for ya to measure the braking moment on the bearings, its what I do
With the felt seals undone get a full 4L contator hang it on a string run over a bar to the end of your steering arms this is equivelent to the normal setting. I work on about 4-6L range due to the bigger wheels and harder use
here this might help

explain my shit discription
Just increase or decrease the shims till you get the right amount, make certain you have the same amount of shims top and bottom
