1. A parking brake apparatus for a vehicle including a vehicle drive train that extends between a vehicle propulsion engine and a vehicle wheel, the parking brake apparatus comprising:
a wheel drum located away from the vehicle wheel and fixedly attached to a drivetrain shaft that extends along a portion of the vehicle drive train between the vehicle propulsion engine and the vehicle wheel;
activatable drum brake components disposed in an interior chamber of the wheel drum and for, when activated, applying a clamping force to the wheel drum to prevent the wheel drum and the drivetrain shaft fixedly attached thereto from rotating and thereby preventing the vehicle wheel from rotating to provide the vehicle with a parking brake functionality; and
an activatable shaft lock for, when activated, locking drivetrain shafts along the vehicle drive train together as a unit, wherein the shaft lock and the wheel drum are enclosed in a common housing.
