Parking Brake fails to work

[TemplarOfSyrinx]

I engage the parking brake.
With the engines on, the aircraft moves.
I disengage and re-engage the parking brake.
The aircraft continues to move.

I have searched the brake function in MSFS to see if anything at all was bound to it.
Nope.

This is just from actuating the parking brake with the mouse.

Please help, this is bloody annoying.

There's very little custom or unusual that I'm doing with the parking brake, so it really should behave like any other aircraft in the simulator. I assume you've tried this with other planes? Despite you already searching for control bindings, my best guess is still that you might have the brake axis bound to hardware, because a toe brake signal from hardware will override the parking brake in MSFS.
