The goalkeeper was called into action again shortly after, tipping a cross behind for a corner before denying Braber's close-range header.
Ten Rouwelaar was beaten 13 minutes in though, as Ben Sahar made a quick break, catching the keeper off his line to fire into an open goal.
Breda continued to press and did find an equaliser shortly before the break, as Uros Matic stole possession in midfield before drilling the ball in from 20 yards out.
Jordens Peters tried to restore Willem's advantage at the start of the second half with a long-range strike, but the goalkeeper watched the defender's shot go well wide.
Sahar and Boateng continued to apply the pressure for the hosts, but Breda did enough to ensure that they did not fall behind again.
However, the home side snatched a late winner when Braber burst into the box and forced a low shot beyond the keeper to clinch all three points for Willem II.
The result moves Willem up to sixth in the table, while Breda drop to eighth.
