What do you mean by driving brake or engine brake in your driving test?
Engine braking means lifting the accelerator pedal, but without taking off the development motive, the internal friction force of the engine and the intake and exhaust resistance are used to form a braking effect on the driving wheel.
It should be an emergency brake and a fixed point brake. The emergency brake is on. The examiner says stop. You'll have to step on the brake and clutch immediately. The point brake is to give you a reference, so you stop there
Engine braking means lifting the accelerator pedal, but not pulling off the engine, using the compression resistance generated by the compression stroke of the engine, the internal friction force and the intake and exhaust resistance to form a braking effect on the driving wheel
Running braking means driving brake, or foot brake, in the course of driving. It is convenient to slow down and stop during the process of moving forward. Not just to slow or keep the car moving. The parking brake is used if the brake failure (brake). When the car has stopped, use the parking brake to prevent the vehicle from slipping and slipping.
