I drive a small automatic car. For the most part, it struggles a bit with steep uphills, and picks up speed when going downhill. That’s to be expected.
But then I noticed some downhills actually slow it down. I’ve noticed during a two-hour motorway trip I often do to visit family, there are some specific downhills, not all, just some, where my car always slows down and I have no idea why.
Ideas?
What happens when the brakes get too hot? Do they gently stop working or can they just explode or something?
Generally much less effectiveness to almost none as they get hotter

Can you continue using them once they cool back down, or does the heating cause permanent damage?
At some point it probably does. And can probably catch fire. Mine were fine once they cooled
Brakes are assholes, when they overheat they can fail basically suddenly. You do get a warning in lower effectiveness or one side braking more than the other, but if you’re not familiar with that feeling, you may not realise it. Also modern cars are made so that everything just feels the same all the time.
You can see it in car races such as in F1. Braking braking, suddenly boom, car is in the barrier.
Yes, they’ll work again after cooling down unless they’re shit and got deformed, or you crashed.
That’s why it’s important to have brakes checked regularly, you get little to no warning in modern cars. Same with clutch and a bunch of other mechanisms.
