Abstract
An auxiliary release apparatus for use with a hydraulic pressure releasable brake having a principal source of hydraulic pressure which comprises an auxiliary source of hydraulic pressure selectively connectible to the brake for releasing the brake when the principal source of hydraulic pressure is not operating. The auxiliary release apparatus includes a manual pump device for interrupting communication between the normal pressure source and the pressure releasable brake when the pressure source, as a pump, is not operating, and for manually pumping through a by-pass circuit pressure fluid to the pressure releasable brake.
