The parking brake of a vehicle is operated by a power-generating generating actuating unit,. For maintaining the function of the parking brake in the event of a failure of the power operating device,, an emergency operating device,is provided which can be operated by muscle force. Both operating devices,have mechanical transmissions,which act upon a common threaded spindle,for tensioning and releasing the parking brake. By way of the mutual self-locking design of the mechanical transmission,which depends on the type of operation, it is achieved that both operating modes (power or muscle force) can be carried out in any sequence and without any limitation of the adjusting path(s).
