A hydraulic brake apparatus, a movable barrier apparatus, a hydraulic brake kit, a method of stopping movement of a movable barrier, and a method installing a hydraulic brake assembly are described herein. A selectively operable piston mechanism converts rotation of a drive shaft of a movable barrier into hydraulic pressure used to operate a brake configured to stop movement of the drive shaft.
