Handbrake adjustment is through any of the rear wheel bolt holes, although I would suggest removing one side first. This will let you see the parts and how they interact, if the shoes are too worn and genrally make a decision on how much of a service is required. If it looks good when you check the first side (I doubt it) the you need only adjust the second side as you have a picture in your minds eye of what is going on.
