As A Tailshaft Parking/emergency Brake
Drum brakes have also been built onto the transmission tailshaft as parking brakes (e.g., Chryslers through 1956). This provides the an advantage that it is completely independent of the service brakes—but suffers a severe disadvantage in that, when used with a bumper jack (common in that era) on the rear, and without proper wheel blocks, the differential's action can allow the vehicle to roll off the jack.
