Do you see two bolts on the backside of the cylinder?

Actually theres only 1 bolt on the bottom and a pin on the the upper part. Does the pin come out or is it swing mechinism?

Well first of all.
If the car has drum brakes take the tire off and on the back of the hub at the bottom there is a small slit (it may have a rubber bootin it) take the boot out. Inside ther is a small gear with teeth on it take a flat head screw driver and put it on the teeth and turn the gear up or down to loosen it till the drum will come off.

There is a special tool needed to back in the self-adjuster nut in the center of the wheel hub assembly. This nut has to be backed in so that you can slide open the caliper sufficiently to be able to remove the old brake pads and install new ones. The nut is embossed with a shape like an hour glass (as opposed to, say, a Phillips or slot shape). The tool will snap into a 3/8" socket driver and with this, will then fit into the grooves to permit you to turn and back in the nut. In Canada, I found a multi-tool that did the job at PartSource. It was under $10. Ask at any reputable auto parts supplier - they should have it.
