Nether what you should do is just take your foot off the gas and let it roll down the hill to its destination.
My answer:When going downhill it may be necessary to slow down to maintain steering control. Using brakes only on a long steep decline can cause the brakes to heat up and fail. Any gasoline engine or a diesel engine equipped with a "Jake Brake" can provide additional braking without heating the brakes. With many automatic transmissions it is necessary to manually select a low gear. Manual transmission drivers will do this automatically.With 2WD vehicles there are additional considerations when using engine to brake in slick conditions:
Regardless of front or rear drive, it is usually best to cease engine braking before entering a curve. The regular brake and especially ABS will distribute braking more equally and are less likely to cause understeer than FWD engine braking or oversteer compared to RWD engine braking.
yes
You should brake at the top of the hill and slow down to a speed where you can change down to the next lowest gear. Anticipation is most important, as you may need to change down again to the next lowest gear. Engine braking helps to prevent overheating the brakes, and also assists vehicle stability on steep hills.

The engine size should not matter when going down a hill, as long as you dont put it in too low of a gear and over rev your engine.
Applying the clutch while driving down a long steep slope can lead to a loss of control and increased wear on the vehicle's brakes. It disengages the engine from the wheels, removing engine braking, which is crucial for maintaining control and slowing down safely. This can result in overheating the brakes, reducing their effectiveness, and potentially leading to brake failure. Instead, it's better to use a lower gear to utilize engine braking effectively.
Not using the engine brake while driving on steep downhill slopes can lead to increased wear on the vehicle's brakes, reduced braking effectiveness, and potential overheating of the brakes, which can result in brake failure and loss of control of the vehicle. It is important to use the engine brake to help control speed and reduce strain on the braking system when driving on steep downhill slopes.

Overdrive should generally not be used when descending steep highway hills. In overdrive, the transmission is geared for fuel efficiency, which may not provide adequate engine braking to control the vehicle's speed. Instead, using a lower gear helps maintain better control and reduces reliance on the brakes, preventing overheating and potential brake failure. It's safer to downshift to a lower gear to manage speed effectively on steep descents.
It depends on the length and steepness of the gradient. On a short slope, or one that is not very steep, use the brakes. But not continuously. On a long or steep slope (as in going down a mountain), the brakes could overheat and stop working before you got to the bottom, or even burn up. In this case, it's best to use a lower gear and get the engine to do the braking, keeping your brakes cool in case you need them to stop. In some extreme cases, you may find that even the lowest gears will not sufficiently slow your vehicle, due to weight, slope, or other factors. In extreme cases, a sustained high RPM in the engine can cause damage. You should therefore avoid routes which constantly tax your vehicle's limits in favor of less steep alternatives. In many areas, heavy vehicles are not allowed on the steepest sections of some highways.
I could be your rotors are need to be reground. Let your brake man check out your brakes.
No
Yes. The only times you should not use overdrive is when towing, such as a heavier trailer, (this saves overworking your transmission), and when descending steep hills, (this saves your brakes some as the engine/transmission does some of the braking as well).
