ATR Prop brake is visual only and does not actually have an effect

Do you have the same issue if you follow the OP’s steps to reproduce it?

YES

Provide extra information to complete the original description of the issue:

Prop brake appears to not actually do anything as it is possible to taxi with hotel mode by moving the power levers forward this also appears to affect other locks like the gust lock where the simulation is only visual. The props also do NOT feather properly and the aircraft can still move with feathered props
