If you have the "Brakes" message disabled in your fs2002.cfg (line show_brake_message=0), the gauge doesn't detect when you set the parking brakes.
- Make sure FS2002 is not running.
- Open file ...\fs2002\gauges\rcb-gauges\PushbackStates.xml with NOTEPAD.
- Change each occurance of the word INDICATOR into POSITION (7x)
- Save&Close the file.
Now the gauge will always work, whether you have the "Brakes" message enabled or not.
