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

Short bursts heat up your pads quickly, but allow them to cool back down in between.
Continuous braking keeps the heat on.

Hm, yes, but total amount of heat is constant. Perhaps it cools quicker with bursts and its higher temperatures because of difference in temperature against ambient.

Not all the heat goes into your brake pads. Your rims or discs take much of the heat but also cool down very fast.
