Sounds like a controller issue.
Open clipboard,goto map controls,select the rudder pedals and check the brakes.
you need to move them all the way and let them go back off,check the numbers and see if there is an input,you could check advanced and watch the raw and scaled windows to see if the brakes are moving all the way and back to center.
If you have a dirty pot or frying pan....

it could be giving unwanted inputs that are locking the brakes on.
