Dynamic brakes work by turning the motors into generators through a resistor
grid. This principle is used on many types of equipment including large
overhead cranes. The wheels become the prime mover for the motor acting as a
generator and the electrical load applied
by the resistors applies mechanical load to the wheels causing a braking
action without using mechanical or friction brakes, thus there is no brake
wear.

OK, next question. How do dynamic brakes work? Does the diesel have
to be turning the generator in order for them to work? Does it turn
the generator backwards? Please keep in mind that I am the kind of
guy that has to call an electrician to change light bulbs so don't
tell me all kinds of complicated stuff, ok?
