Narrative:

Upon touchdown the aircraft veered violently to the right as if the brake had stuck. I had zero control over the aircraft as it started to lift the left wing the wind was calm I departed the runway into the grass and had some directional control at that point the aircraft came to rest in the mud with the prop still running but damaged no one was hurt and the plane was towed to FBO on the field. I have never ever felt in my 4900+ hours as if I was just along for the ride and had no control at all. As an after thought I had had it pull to the right but it was not as violent and released after a couple of seconds in a previous landing and should have had my mechanic look at it then but thought that it was just me not quite lined up with the runway.
