I had the same problem when I took the Plus 8 (2001) to technical inspection (TUV in Germany).
Left hand slave cylinder was clogged (rusty). I tried to follow gomog advice to remove the hub. There are two contradictonary advices. 1) remove the hub 2) don't remove the hub.
I couldn't get off the hub. I kept on going w/o removing the hub. Later I found that link for a hydraulic hub puller (10 ton !!)

Replacing the brake shoes is indeed a painful exercise. Having attached the revised slave cylinder and mounted the brake shoes I used a large clamp to hold the shoes in place and could mount the springs. The trick to get the shoes into the right place is to detach the handbrake cable first (near the axle where the other side handbrake cable is mounted to the adjuster)
Then bleed the brake lines, put on the drum and only than reattach the handbrake cable.

PS removing the hub is only necessary when changing to wheel wires or vice versa
