    Heat = friction, so something must be catching somewhere. I'd look towards the calipers as these are the ususal suspects in cases like this.

    Have you got Bosch rear calipers?? - they are notorious for (periodic) sticking. so smouch so that VX changed to lucas calipers on later models. And there is even a modification for those if they start to bind.

    I had a feeling you's say that.

    I'm not sure if the mod, which is fitting damper weights, can be done to bosch calipers - I had my lucas one done under warrenty (even tho i didn't need them) so I've no idea of the price, unfortunately.

    I know a lot of bosch's were changed under warrenty, but your's is out of that now so you'd be looking at paying for it your self.

    No not all - just the ones that were binding.

    VX just swapped ther ones that were experiencing trouble, after all other attempts to cure the problems had failed. Probably they saw it as the cheapest/easiest option, rather than keep trying different "cures" like cleaning etc

    I agree with Ffoeg here, sounds like a sticking caliper. Change them to the Lucas type if you can, just sold a set of rear Lucas calipers, sorry. According to Haynes the rear calipers aren't serviceable, I suspect the piston is sticking but it's unlikely you can repair them as parts don't seem to be available. The buyer of my old Lucas calipers had Bosch and his were so bad he had to put bricks under the wheels to stop it rolling off his drive. I suspect yours are going the same way.

    Do them sooner, rather than later or you'll need another set of discs as well as calipers. Try and find a post 2001 Astra for Lucas calipers, they are clearly marked as Lucas so it's difficult to confuse them.
