Neymar scored twice after coming off the bench as Brazil eased to a 4-1 victory over the United States at Gillette Stadium in Foxborough, Massachusetts.
The visitors went ahead in the ninth minute when Hulk tapped in a rebound, while Neymar doubled their lead from the penalty spot, shortly after coming on as a second-half substitute.
Rafinha showed a quick turn of pace to take Brazil out of sight just after the hour mark and Neymar then doubled his tally for the evening with a simple finish three minutes later.
Reading midfielder Danny Williams pulled a goal back for Jurgen Klinsmann's men in the dying stages but it mattered little to Brazil, who will approach their first World Cup qualifier against Chile next month with plenty of confidence.
While they were able to wear down their opponents as the match wore on, the South Americans were given a slice of luck for their opening goal.
Willian ghosted down the right and his floated cross bounced off the inside of the post, with Zenit St Petersburg striker Hulk reacting quickest to slam home the rebound.
The home side nearly dragged themselves level as Jozy Altidore narrowly failed to get on the end of DeAndre Yedlin's cross, but Brazil were picking holes in the United States seemingly at will.
Brazil failed to make their dominance count as they went in at the interval with just a goal advantage but boss Dunga introduced talisman Neymar and new Liverpool signing Roberto Firmino for the start of the second half.
Neymar was thrust into the thick of the action in the 51st minute after being upended by Stoke defender Geoff Cameron while attempting to chase down a David Luiz ball over the top.
The Barcelona forward dispatched the spot-kick, despite Brad Guzan guessing the right way, and Brazil were 3-0 ahead in the 64th minute when Rafinha turned brilliantly before scoring his first goal for his country, having been on the field for a matter of seconds.
Neymar then finished clinically from Lucas Moura's cross, following poor defending from the United States, midway through the second half as Brazil threatened to run riot, with Rafinha then shooting wide in plenty of space.
The hosts were able to cut the deficit and add a little respectability to the scoreline after Williams' piledriver in the first minute of added-on time but it is likely to have been precious little consolation to Klinsmann.
