You really, really need to lubricate this. You'll have little specks of brass dust all over the place if you don't. I agree with the rest of the post though. It's only a prototype, so you don't really know what will happen. It could be that the transmission with backdrive before you brake anything, or that the wheel (omni wheels don't have much grip) will loose traction with the ground before something goes wrong.
Overall, I really like how small this is. It's perfect to fit in the corner of a robot.
