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.

Famous quotes containing the words emergency brake, emergency and/or parking:

    In this country, you never pull the emergency brake, even when there is an emergency. It is imperative that the trains run on schedule.
    Friedrich Dürrenmatt (1921–1990)

    War-making is one of the few activities that people are not supposed to view “realistically”; that is, with an eye to expense and practical outcome. In all-out war, expenditure is all-out, unprudent—war being defined as an emergency in which no sacrifice is excessive.
    Susan Sontag (b. 1933)

    That’s interesting. Sort of a private preserve for teenagers, huh? I suppose as adults we’re lucky to find a parking space.
    —Kenneth Langtry. Herbert L. Strock. Prof. Frankenstein (Whit Bissell)
