Not a daft question at all
2 ways one is the obvious cable on the caliper or an extra handbrake only caliper
Or the usual way, find a small rear drum setup.. why... 99% of lower market or even some upper market cars have drum shoes inside the disc and use the inside of the disc as a drum
not many people know that and are usually surprised when they find out 
Don't mean to litter your blog with my photos but look at thickness of the disc there's a drum brake in there somewhere
