No, it doesn't use power just to keep the brake on. There is an actuator that activates a physical brake mechanism that sits inside the rear wheels, instead of the traditional cable. It's only using power for a few seconds right after you hit the switch. This is a common feature on new cars, my previous car had one as well.Thank you for the response Regarding the parking brake I have read that since it is an electronic brake it has caused battery drain since it is engaged while the car is off.
