Nolan Patrick had two goals and two assists for the Wheat Kings including the game-winning goal with 5 1/2 minutes remaining in the third period.
Patrick's goal snapped a 4-4 tie in what was another wild third period, with Brandon letting a 3-2 lead slip away before scoring the game's final three goals.
In the end, though, Brandon emerged with back-to-back home-ice wins to start the Best-of-Seven series.
"It's huge going into Red Deer with two wins, obviously. The guys came out and played really well," said Brandon captain Macoy Erkamps on CKLQ's post-game show, "We know that in the Regina series that they were a different team at home so we have to be prepared for that but we're feeling really good going into Red Deer."
Jayce Hawryluk added four assists for Brandon while Tim McGauley and Tyler Coulter added a goal and an assist each.
"There's guys that are going to get goals and assists at the end of the night but there's a lot of hockey that's just about doing it the right way, playing well and helping your team win," said Brandon GM/Coach Kelly McCrimmon, "I thought Jayce tonight not only, in addition to the four assists he got, I thought he and his line did a really good job of playing the game hard and playing it well."
Kale Clague and John Quenneville, into an empty-net, also scored for Brandon while Luke Philp had a goal and two assists for Red Deer.
Jake DeBrusk, Colton Bobyk and Haydn Fleury had the other goals for the Rebels.
Rylan Toth stopped 35 shots in the Red Deer net while Jordan Papirny made 27 saves for Brandon.
The series now shifts to Red Deer for Games Three and Four on Tuesday and Wednesday.
