Josh Hershman killed the game when he slotted home a delightful through ball from Ellis, while Alex Hershman also hit the bar from 30 yards.
Delighted Brady boss Joel Nathan told JC Sport: "This was our final game before the Peter Morrison final in a couple of weeks and the main thing was to win, keep a clean sheet and keep the pressure on for a top three finish.
"Yes we were missing a couple of players today, but the boys who came in did very well and now Josh and I have some tough decisions over our starting line up."
Raiders manager Rob Richman told JC Sport: "It was just a poor day from start to finish. We lost two players in the build-up to the game and then David Rhodes not even five minutes into the game.
"That being said, we still had enough quality on the field to give Brady a match, but in truth we were poor and Brady didn’t have to do too much to beat us.
"We will knuckle down and work hard as we need to scrap and battle for a few points which will make us safe."
