Total Brake Toque Vs Brake Torque

May I know the difference between Vhcl..Trq_Brake, Brake.Trq_WB_ these quantities?

when I attached scopes on these quantities (Vhcl..Trq_Brake = 3* Brake.Trq_WB_) one is always a multiple of other. I am wondering how!

Good morning,
here the definition of the variables

If the brake pressure distribution is more on the front axle what you may see is these split between the front brake torque and rear brake torque, this is an example with 60% brake applied

Hope this clarifies your question
