VW CC EPB caliper rewind tool.

[Sensibleboy]

Can anybody recommend a cheap way of rewinding the rear calipers on my VW CC? I.e. what's the cheapest plug in tool that will do this?

I've got rewind kits for normal calipers but the motorized handbrake needs to be electrically rebound.

I've heard connecting a 9 volt battery to the terminals on the caliper is ok but I suspect there's more to it than that.

Thanks. I'd hear things about it resetting the open and closed position etc, as if the settings needed to be learnt/calibrated by the car. If none of that is necessary though then I'll try the 12v approach.
