There is a complete section of the file missing, which usually is found just after the Friction lines. It defines the brakeforce and some other parameters.
This is from the Milw 261
BrakeEquipmentType( "Triple_valve, Auxilary_reservoir, Emergency_brake_reservoir" )
BrakeSystemType( "Air_single_pipe" )
MaxBrakeForce( 81.56kN )
EmergencyBrakeResMaxPressure( 110 )
TripleValveRatio( 2.5 )
MaxReleaseRate( 2.27 )
MaxApplicationRate( 1.717 )
MaxAuxilaryChargingRate( 1 )
EmergencyResCapacity( 2.604 )
EmergencyResChargingRate( 1 )
BrakeCylinderPressureForMaxBrakeBrakeForce( 64 )
You will most probably have to make some of these figures match those found in the braking section further down in the engine section of the file, things like charging rates and release rates.
Beer is not a matter of life or death, it is much more serious than that.
