How hot do race car brakes get?
F1 brakes can regularly reach temperatures of between 400°C and 1000°C, but it varies throughout the race. Brake temperatures can be managed with cooling ducts, vents and holes, but if temperatures above 1000°C persist, oxidation of the brake discs and brake failure can occur.
How hot is too hot for brakes?

Does hot weather affect car brakes?
Brakes Need Heat Dissipation
The high heat that develops in vehicle brakes damages brake parts over the long haul. If your brakes grow extremely hot, and the heat cannot escape from the brakes, your brake system is prone to damage, unreliable performance, and eventual failure.
Is it normal for brakes to get hot when new?
You would be surprised, but it is quite common for them to smoke after replacement. Brakes getting hot after new pads is known as the polymerization or curing process. Normal breaking leads to the heating of the friction materials which makes the pads go through this final curing process.
Can you put water on hot brakes?
