PMDG 777 does little continuous brakes

when i am on the ground the 777 does little brakes that are annoying and slowing me down when taxiing or for takeoff.

in this video you can see the pedals moving and the aircraft stopping and going.
any idea why it is like this?

Contact our support team at support.pmdg.com, and we will sort that out for you.
