Hi I downloads the pmdg 737 ngx and I think it is an amazing product with great detail. I am able to do a full autoland but after landing when I have turned the autothrottle and the flight director off, I turn off the runway and I use my rudder pedals to turn and brake but after landing they don't work as well as they do when I turn before takeoff and the brakes don't work at all, even though it says down the bottom 'brake'. Plz tell mine if they're is something I can do because I can't taxi

there must be brake failure. you can turn off the brake failure via fmc. otherwise if you make a hard landing, you may suffer damaged brake problem.

No I checked that and there are no active failures
