This VR simulation incorporates a full brake system including what it starts with — the pedal, and includes the other components of the system such as the brake booster, brake fluid reservoir, etc.

It has grabbable Info panels which can be moved to any spot.
It also has grabbable objects / snappable zone interactions — for placing the tire onto the car after everything is examined.

It utilizes the Unity XR Interaction Toolkit for the movable Info panels. And the VR interactions and transitions, some of the 3D models, and animations were created using other tools in Unity.
