What is a dual circuit brake system?

That a car is equipped with a dual circuit brake system means that the brake system has two independent systems operating on separate circuits. If one brake line is damaged or starts leaking, there is still another brake line which allows braking on some of the wheels.

All motor vehicles in Sweden must also be equipped with two mutually independent braking systems: service brakes (also known as foot brakes) and parking brakes (also known as hand brakes).
