The rear shoes have a Japanese type magic screw adjuster, you screw it closed when you fit new shoes. Then with the drums on you press the brake pedal hard about 500 times and they reset by magic (I know exactly how they are supposed to work, I just don't see why they should) The adjusters are handed and have opposite threads.
You are unlikely to need rear shoes though, unless you drive with the handbrake on the rear brakes do hardly anything compared to the fronts
You MUST threadlock the hub nuts if you don't fit new ones(like Nissan recommend) or the back wheels will fall off.
I can say with hand on heart, no cars that I've owned has had the rear shoes replaced whilst in my possession, due to wear. My old Nissan Sunny never had new rear shoes in nearly 200,000 miles. They were always checked at service, and pre MOT.
Is there anyway of checking the rear shoes on a Note visually.?
Here is a nice picture. The magic adjuster is item 4
If the shoes go out too far the magic works and little levers gradually turn the screw thread to make the adjuster longer
Notice that the assembled view is the opposite hand brake to the exploded one. AND they have put the magic adjuster opposite ways round .If you do start messing, take some photos before you move anything, to aid in assembly, and don't ever strip both sides at once
