Brake axis are not set for me, i have the same in the Airbuses. Cant remember if 737 too but i think so.
I have deleted every single command that has to do with brakes, from keyboard as well from other hardware and remapped only “Brakes” to a joystick button, same.
I unplugged all hardware besides keyboard and mouse, same.
Ive tried the Fenix, same.
PS, no rudder pedals here.
What hardware are you guys using? TM Airbus here.
What ive noticed, whenever this issue starts (after pushback), if i go to controls and search for buttons, it wont work anymore reliably. It searches a button but if it got found, the UI doesnt stay active and returns same moment again. It can also happen that it doesnt find the button at all! Like you move the parking brake while scan for input is active but it wont be found.
THen you go into a GA plane/restart the flight it suddenly finds it agin and one can also see the parkbrake move in plane.
I mean, usually if you do that, you get the UI that shows the conflicts and where it lets one change all kinds of settings. This doesnt work anmyore correctly until one leaves the flight.
Im so tired of this.
