The hydraulic diagram shows the vehicle in the normal braking mode of the base brake hydraulic system. See Fig 1. The diagram shows no wheel spin or slip occurring relative to the speed of the vehicle. The driver is applying the brake pedal which builds pressure in the brake hydraulic system to engage the brakes and stop the vehicle.
