The U's, who won by the same scoreline at Maldon & Tiptree on Friday, hit back from behind after Sherwin Stanley put Brentwood ahead in the 40th minute.
But Colchester replied instantly and secured the win with two goals in as many minutes.
John-Joe O'Toole headed the first 30 seconds after the U's went behind and then Freddie Ladapo slotted past the goalkeeper to make it 2-1.
