How does breaking affect brakes? (programming.dev)

I was always wondering this. Imagine a steep descent. What is better for brake wear - braking constantly or more powerful just at the end? Anybody knows? Goes for both rim and disc brakes

Physics says both use the same amount, just one is spread out more and the other is all at once. I don't have the formula, but basically it takes the same overall effort to stop an object regardless of if it's slowly or very fast.

If you however travel at greater speeds, you loose more energy to air resistance since it squares with velocity. If you only brake at the end you will have lost a greater amount of energy to air resistance and less energy will go into the brakes.
