When stepping on th brakes you are actually opening a valve that permits the engine to suck air from the "Servo" of the braking system to give your step on the pedal a greater force.

The engine hunts because the carburetor is not well tuned at idle, so any change in air quantity coming into the engine block disturbs the balance. It wouldn't hunt if you step very slightly on the gaz pedal simultaneaously (try it when parked).
