For what it's worth, a 757 at ground idle produces around 3000 pounds
thrust
per engine - you can back them using the reversers, but you can't go full
power as the re-ingest the exhaust gasses.

And when you're backing you must always use forward thrust to stop, and
not
the brakes - anyone guess why?

The disk brakes would roll our of the calipers?
