Not if the frame comes away from the car.An inertia handbrake mechanically locks the brakes and will stay that way until over-ridden
The hitch assembly handbrake put on the brakes via a Bowden cable by pulling on the hitch assembly handbrake.
If the frame departs the car then the brakes will be applied momentarily then the Bowden cable will snap and release the brakes meanwhile the A frame and it's handbrake are still attached to the towbar.
