Narrative:

Shortly after landing; the plane started to shake substantially and pulled toward the left. I'm not sure whether I did not apply right rudder quickly/strongly enough; or if there was an issue with the plane that contributed (e.g. Right brake less effective then left); but in any case I was unable to maintain sufficient control and the plane left the runway on the left side; going through a small section of grass before re-entering a paved taxiway. It is possible that the fact that I was flying with a friend who is a fairly new student pilot affected the quality of my performance; as I could have been worried about what he would think of my landing compared to how his instructor has been teaching him. In the future I will be more aware of the need to continue 'flying the plane' even after landing; and less concerned with the possible judgment of passengers.
