When the piston is activated, it pushes that aluminum bar you see in the video into that third plate, which is mounted parallel to the mecanum wheel. This pushes the rubber piece into the wheel, braking the roller.
The plates are on the same axle as the wheel and are spring loaded, so when the piston retracts, the plate comes off the wheel, unbraking the roller.
