Symptom description indicates an electrical fault and I agree with Rasmataz about the brake switch.
On the brake pedal there is a bracket with a stopper. Where it rest is the brake switch. It has 4 wires, 2 for the brake lights and the other 2 for the cruise control.
When brake pedal is depressed, the brake light circuit would have continuity whereas the cruise control circuit would be open. They work in reverse order.
