OK here is the picture tutorial on replacing the pads.
Removing the drums varies. Here is a link to removing the drums off my car 2006 aveo:
0) New pads and the drums removed. Jacking under the rear axle beam is a good spot to pick the entire rear of the car. Assuming no bleeding needed.
1) Use the pad with the e-brake and flip up the brake lever like so:
Using two pliers pull the spring away and the cable towards you, then use the magic of your feet to maneuver the attachment point onto the cable.
Rotate the brake pad in place with the e-brake behind the brake pad.
Put the retaining pin and spring onto the pad for the e-brake pad.
Mount the adjuster with the tooth out and gear towards the front. Pay attention there is LH and RH stamped into the metal. The gear teeth are situated to rotate down towards the outside. Again a picture is worth a thousand words.
Mount the bottom spring onto the e-bake pad and onto the front pad. This has to be done at this stage otherwise you will NEVER be able to stretch that spring into place.
Rotate the pad into place; the bottom spring will kinda keep it there. Mount the retaining pin and spring.
