Well, I only fly them, but I thought I said it was a maintenance issue. Maybe I wasnt clear enough. If the lock doesn't disengage the aircraft won't steer. If the leg doesn't compress then the lock won't disengage. The wheel needs to be on the ground with some weight on it to compress. It doesn't need brakes to do that if the leg is properly set up. It does need the pilot to relax back pressure on the stick as the aircraft slows down after landing.
