Corsa - C Brake Shoe Problem

[Spleurker]

I have a Corsa -C and recently put a new brake shoes into the rear
hubs.
This weekend I started getting a noise from the nearside drum during
travel, which disappeared when I pulled the handbrake slightly.
I took the drum off to investigate and found that the shoe facing the
front of the car had slipped off the cylinder at the top, it had moved
toward the back plate not toward the drum. I put everything back as
it's supposed to be and all was ok.
The same problem has appeared again today!!
Has anybody come across this before and is there anything I can do to
stop the shoe moving away from the cylinder?
Cheers

Have you put the adjuster on correctly? there is a little spacer that goes
between the shoe and the adjuster - it doesn't always come with new shoes so
you have to swap it from the old one.
