1. Support the car
2. Remove the wheel
3. Undo the retaining screw that holds the disc onto the hub. Screw one of the wheel bolts in a few turns to keep the bolt holes lining up with the hub.
4. Undo the caliper retaining bolts (can't remember if the shock absorber is in the way for this one, if it is you have to put a jack under the hub to compress the spring slightly when you release the shock absorber bottom mounting.
5. Very carefully ease the caliper off the disc, there should be enough give in the steel brake pipe to allow you to do this and suspend the caliper behind the disc.
6. Using a torch & screwdriver peer through the hole provided in the disc and undo the handbrake adjuster enough to pull the disc off.
And reassembly is the reverse of disassembly. (or whatever the phrase is that Haynes used to use
)
