Had no left brake after landing XXL. Pilot started drifting right and eventually gave controls up and told me he didn't have brakes. I tried pumping the brake but it wasn't working and was fully pressed. Instead of going in the grass I slammed the right brake once it was slow enough and spun the plane out. Once we came to a stop and after continuous pressing of the brake; we regained control and we're able to exit on Taxiway 1.
