I'm willing to bet that one of the robots involved in the pushing match (either yours or the robot trying to push you) will lose traction before the motors back-drive in brake mode. Especially considering a vast majority of pushing doesn't occur head on (a great deal of it is rotational in the world of FIRST, something that a braking mechanism that locks the wheels won't help with). If you want a system to prevent torqued out of position, it would have to be in contact with the playing field rather than the wheels.
Mechanical brakes (such as disk brakes) may be a valid solution for other aspects of the robot, such as arm and shoulder joints.

My post was a follow up to M. Krass's.
As for what you are saying about brake mode: it is not
that strong. It does provide some resistance to motion, but not alot. Brake mode seems good for allowing the robot to stop on a dime, and also for
helping to keep an arm stationary. Break mode may not help much in a pushing match.
