ABSTRACT:
A dual function brake and manual drive actuating system for selectively holding a rotatable member of a drive train and manually driving the drive train. A support structure is provided, with a brake operatively associated between the support structure and the rotatable member for holding the member against rotation. A common release member is operatively associated with the brake. A fluid retracting mechanism operates against the common release member to selectively hold the brake in disengaged condition. A manual retracting mechanism also operates against the common release member to selectively hold the brake in disengaged condition. A manual drive is incorporated in the manual retracting mechanism for manually rotating the rotatable member when in the disengaged condtion.
