Trucks use air-brakes to stop. An air compressor in the truck sucks in air and squashes it. When the driver presses the brake pedal, the squashed air travels along coiled air lines. It pushes brake shoes against the wheels, slowing them down.
Trucks take longer to stop than passenger cars.
No, the larger the vehicle the harder it is to stop.

Semi trucks often use compression brakes. When activated compression brakes open valves in the engine, slowing down the engine and bringing the truck to a stop. Non-semi trucks use disc brakes to stop. A common type of brake system used in big trucks is the air operated "S" cam.
