The South Americans hit back from their shock opening-game defeat to Iran by thrashing New Caledonia in Jakarta while registering a staggering 81 shots.
New Caledonia were already reeling from a 10-0 thrashing by England on Saturday and Brazil almost matched the Young Lions with their own devastating display.
Keen to put the defeat behind them, a riled-up Brazil set out the stall early on, dominating with waves of attacks on their opponents.
But they were made to wait until the 28th minute to break the deadlock when Rayan headed the opener.
The floodgates quickly opened when Estevao curled home a fabulous free-kick before Luighi produced a purler of his own, a drag-back before striking into the top corner.

It was more of the same in the second half when Kaua Elias headed home Brazil's fourth before Rayan added another from the penalty spot.
Brazil captain Vitor Reis headed his side's sixth and Joao Victor fired in another from the edge of the box.
A relentless Brazil concluded the scoring when Kaua Elias notched twice more to complete his hattrick before the final whistle put New Caledonia out of their misery.
Next up for Brazil is a meeting with England on Friday which pits the tournament's last two winners.
