If you're full rudder deflection and the airplane is still turning the other direction, then your only resource remaining is brake. If you're having to use brake on every landing and the airplane is pulling left during taxi, then something's wrong, and the airplane shouldn't be flown until it's corrected.
Getting in the habit of using brakes for landing, especially in conventional gear (tailwheel) airplanes, especially this early in your training, is a bad habit. Especially when it's not for stopping, but just for directional control.
I've done many takeoffs and many landings in which considerable brake was required for a strong crosswind in tailwheel airplanes, but it's an advanced technique that can get you in a lot of trouble very quickly if not done properly.
