In most cases, using the "brake" feature on drive controllers is a bad thing. The drivers feel they have no control over the robot and just when you least expect it, bam, the brake causes your robot to tip over.
Ligthwave, if you look on the IFI website, there is a pinout for the competition port and a diagram to make a switch that will disable the robot, enable for competition or enable auto mode. It is a very simple device to make, and is absolutely necessary in practice.
