If the trailer breaks away from the tractor on a dual air brake system, what applies the brakes on the trailer?

A. Emergency/parking spring brakes on the trailer
B. Tractor's foot brake pedal
C. Tractor's service air brake system
D. Trailer's handbrake

Answer :

Final answer:

When a trailer breaks away from the tractor, the emergency/parking spring brakes on the trailer engage to stop the trailer.

Explanation:

If the trailer breaks away from the tractor on a dual air brake system, the brakes applied on the trailer are the emergency/parking spring brakes on the trailer. These emergency brakes are designed to automatically engage if the air pressure in the brake system drops below a certain level, such as in the event of a separation of the trailer from the tractor. This safety feature ensures that the trailer will come to a stop even if it disconnects from the tractor. Unlike a hydraulic brake system where you press a pedal and it pushes hydraulic oil into the output piston to engage the brakes, the air brake's emergency system is spring-activated, relying on stored energy in the springs to trigger the brakes.
