Formula One cars put tremendous strain on the drivers who pilot them. There are tremendous g-loads in nearly all directions thanks to the insane acceleration, cornering and braking ability of a modern F1 car. There are also incredibly high demands of the parts of the car themselves, as they have to work well and work consistently. Brembo knows this, as it supplies the components that haul in all of the speed a F1 car produces.
Brembo tests its brakes with a setup that allows them to run a rotor up to high speeds, and then clamp down upon it just as the system would during a race. In the lab though, Brembo can do it over and over again for as long as it desires to see just how much they can torture the components. This means the brakes will see temperatures ranging into the thousands of degrees, depicted beautifully in this video from YouTube user OmniCorse.it.
The numbers associated with F1 simply can't apply to the world of the street car. We don't see 5 g of braking, acceleration to 60 mph from a standstill in two seconds, and complete pit stops in almost the same time. Also, we don't have to deal with Bernie Ecclestone... so we've got that going for us, which is nice.
