I have heard that too, but it, of course, depends a lot on the speed.
I guess the 1G deceleration is at near top speed.

The reason hotter is better is because temperature difference is what
drives the heat transport away from the brakes. If you can build
brakes that can handle more heat, you can build them smaller and
lighter, which are good properties in F1.

I have also read that many of the drivers did not like the carbon
brakes when they were introduced, because they were considerably more
difficult to modulate properly than the steel brakes.
