A hydraulic power take-off is provided for use with industrial drives. The hydraulic power take-off has a multiple-force brake system that facilitates actively slowing large inertial loads associated with a heavy rotating mass of an industrial machine. The multiple-force brake system applies different braking forces at different times to control deceleration of the heavy rotating mass in the industrial machine to reduce its stopping time. The multiple-force brake system may include a clutch assembly and a brake assembly. A control system may control the clutch and brake assemblies to provide the multiple-force brake system a relatively higher energy brake engagement state and a relatively lower energy brake engagement. This may include alternating between the higher and lower energy brake engagement states to pulse between high and low pressure braking to facilitate cooling of the system while slowing the large inertial loads.
