Former McLaren speedy Lewis Hamilton out-paced by his team-mate Nico Rosberg in recent few races, Nico consistently seize three Pole position and set Monaco Grand Prix dominant victory.
"I think it is quite a subtle thing, but it will just be time quite frankly" Brawn said, "It is just working out how the driver communicates, how you understand what it is he wants to achieve, how you tune the car to suit his needs.
"[Hamilton] might vary from Nico in terms of what he is looking for. Nico has been with the team four or five years and he knows exactly what buttons to press.
"Lewis is developing his understanding of that; of what person to go to if you want to discuss that, or who you go to if you want to debate certain aspects of the car. We have a very good group, very experienced people, working with Lewis. It just takes a bit of time."
