A disconnectable vehicle driveline having front and rear axle assemblies and a power take-off unit (PTU). The PTU includes a coupling, which is configured to selectively transmitting rotary power between an input shaft and a first gear, and a brake element. The coupling includes a first coupling portion, which is coupled to the input shaft for rotation therewith, and a second coupling portion that is coupled to the first gear for common rotation. The second coupling portion can be translated into and out of engagement with the first coupling portion. The brake element is configured to engage the second coupling portion when the second coupling portion is not engaged to the first coupling portion to thereby resist rotation of the first gear and elements of the vehicle driveline that are drivingly coupled to the first gear.
