: We haven't tried the brake at all, but there is a
motor that we certainly could benefit from the use of
it. I have a question about it though. If what it
does is basically short the terminals, will it drain
the battery?

It only shorts the output to the motors and doesn't
affect the input from the battery. You can easily see
this
effect on the fisher price motors, if you have a free
one.

First try turning the output shaft when the motor is
disconnected. It should be possible to backdrive the
motor. If you then get someone to connect the two wires
coming from the motor, you will find that is MUCH
harder to turn the output shaft.
