What are the two tanks typically found on a straight truck's air brake system called, and why does it matter that they're separate?

Pick an answer

1. Primary and secondary tanks, kept separate so a leak in one system doesn't leave the vehicle with no brakes at all
2. Left and right tanks, split so each side of the vehicle has its own dedicated horn, a naming pattern some drivers assume mirrors the dual air gauges
3. Hot and cold tanks, kept apart purely to balance the vehicle's weight distribution
4. Front and back tanks, separated only to balance the weight of the vehicle evenly
