How to fix a 1990 Ford EA Falcon Handbrake?

Most cars that have rear disc brakes use a drum brake inside the back of the rotor. Where does the hand brake cable go? If it goes to the caliper, the only thing I can suggest is apply the brakes with your foot and then while holding the pedal down, set the hand brake. If it doesn't go to the rotor, it is and adjusts like a regular drum brake.
