DAve, that's just the thing. After I press and release the brake,the CC releases, but then it won't switch on again. It won't set, accelerate, decelerate, resume. Nothing. I have to swtich the ignition off and then on again. Then the CC Works until I use the brake. If I use the "off" on the CC lever, I can resume again without restarting the car.

That's why I think it must be some bad wiring in the brake pedal - the system only becomes non functional after the brake pedal is pressed.
