How can I connect an Hydraulic connection to my Tire model ?

Hello,
I'm doing a "kind of" park-by-wire ( https://en.wikipedia.org/wiki/Park_by_wire ) on Simulink using Simscape and Vehicle Dynamics Blockset toolbox, I'm only at the beginning.
This is my first Simscape model so there might be more mistakes than I think...
Basically this is what I've done : https://imgur.com/a/ULviYrW
So I have a Controled Voltage Source (12V) that powers my Generic Linear Actuator (it's just an electric actuator). This electric actuator is pushing another plunger ( Double-Acting Hydraulic Cylinder) which is pushing brake fluid into my wheel disc brake.
My main issue here is :
How can I convert this red connection (from A port of my hydraulic cylinder to my Brakes) ? It's a hydraulic connection and the wheel's brake port is in Pascals so I don't know why I can't connect them.
I have tried to add a Hydraulic Pressure Sensor which has a physical output but I don't know if that is the solution, it seems a bit tricky.
I have also tried to use Simulink PS-converter but it won't connect either.
Thank you for reading !

The brake pressure port at the wheel model needs a simulink signal. The Simscape hydraulic system outputs phsical signals. You need to convert the hydraulic signal with a PS-Simulink Converter and connect the Converter output to the wheel.
