F1 2015 Settings Thrustmaster T150

[Leg3nd]

I was wondering if there is anyone here that is racing with this Wheel and pedels?

I dont seem to understand why the breaking with no assist seams to lockup with only 50% pressure on the pedel, even when in the Windows controller settings is just aplying 50% on the sensor, and also with the Telementry data show the same.

I have been playing around with the breaking linerity but dont seem to feel any diffrence from 0% -100% anyone that can tell me what the linerity affect the breaking ?
And if they have any tips on how to manage the breaking in death. i would be happy.
