Abstract: A relatively simple hydraulically operated disc brake mechanism for drive systems which store torsion by reason of being under torque is disclosed. Certain drive systems such as the drive strings for deep well submersible pumps store considerable torsion due to torque and elasticity. Such torsion must be controllably released if drive power is interrupted. The disc brake mechanism includes a housing that defines a reservoir for lubricating oil for the bearings of a shaft that drives a bi-directional hydraulic pump. When the shaft turns in an operating direction, the pump conveys the lubricating oil in a closed circuit by way of a control manifold through the brake mechanism and back to the reservoir, without activating the brake mechanism. This flushes the complete lubricating oil circuit including the control manifold and the brake mechanism to prevent accumulation of gas pockets therein at locations of little or no fluid flow.
