Atletico Madrid midfielder Arda Turan had a shot saved for Turkey before Brazil added a third before the break.
This time, Neymar turned creator as he dribbled his way down the left before sending a cross to the far post, where Willian was on hand to finish from close range.
Brazil wrapped up the win early in the second half when Willian and Neymar exchanged passes, before the latter held off a challenge to roll the ball into the far corner.
