Yet another parking brake thread!

Hi folks. My parking brake was causing some impressive squealing noises while driving along with it supposedly off. Both rear discs were very hot at the time too. Surprisingly, it didn't seem to be causing any drag as nudging into neutral and coasting didn't result in the speed bleeding off much at all.
Stripped the rear brakes down this morning to find;
1. Drivers side disc did not want to let go of the parking brake shoes. Slight lip inside disc but nowhere near enough to cause that.
2. The 'actuator' on the wheel end of the cable was fairly well seized.
3. After stripping, cleaning and rebuilding that side it was still very squeeky/squeely so I stripped it again and on the second attempt there was only a slight high point at a certain rotation of the disc.
4. Stripped the other side and the disc came off easily. Quite a lot of old looking corrosion on the parking brake contact surface indicating that it was doing nothing, but the disc was hot when I discovered the issue. Stripped and rebuilt with minimal hassle.
5. The shoes don't touch the block adjacent to the actuator and I'm tending to think that they should. There's a gap of around 2 or 3mm on each shoe.

Suggestions anyone? I've been for a run and, without using the parking brake, all is well with no noise or excess heat. Starting to think that the issue was the brake binding/not releasing. I'm a bit loath to use it at the moment! Had a look at backing off the tension due to the shoes not sitting on the block but I really can't be bothered removing the passenger seat to get enough access to the adjuster! Oh by the way, this is an '11 plate model. Thanks all.
