Hi Jan,
Thank you for reply. Animation of braking pedals is absolutely unimportant, it doesn't touch standard procedures ;-)
I newly have tried super clean installation of latest X-Plane and IXEG 737, no others plugins or add-ons, default joystick/key assignments, no special configuration. Battery was on, trying V and B keys repeatedly many times, the needle stayed on about 3000 PSI. Brakes are working ok.
Beside this I have problem with FUEL QTY indicator test and LE DEVICES test (AFT OVERHEAD PANEL). They seems also inoperative.
