Technique: the brakes of Formula 1 cars

Despite the fact that the operation in great lines just matches that of the brakes under your leasebak, there is enough to tell you about the stops on the highest level be used.
The basic principle remains even in the technically advanced Formula 1 is quite simple, namely brake discs, which with the help of hydraulic systems through the brake pads to be slowed down. Braking is not much more than the conversion of kinetic energy into heat. Therefore, you see the drives on the faster circuits, or during races in the dark red glow.
That last is no accident. The carbon discs in F1 are used, temperatures reach up to 1,200 degrees. For comparison: for ordinary steel disk is at 500 degrees, to stretch it out. That’s also the reason for carbon fibre disks. This material can have much higher temperatures than, for example, steel discs, reducing the risk of fading (decreasing braking effect at high load) a lot less.
Small disadvantage: the operating temperature of such brakes is quite high. Stamp on the left pedal while the disks are still (too) cold, and there happens almost nothing. Therefore, are disks made from solid carbon so not suitable for straatgebruik. For that reason, it is the more exotic cases for the public way use is made of carbon/ceramic discs.
As soon as the disks of a Formula 1 car on temperature (at least 300 degrees), it is wise to have the brake pedal what is respectful to treat. A little F1 car while the brakes almost 6G. An average street-legal car loses, for example, at close to 1G all the grip.
There we have a comment to make. As soon as a driver in a F1 car at high speed, the gas is released, the deceleration due to air resistance and engine brake that is about 1.5 G. this is so harder than a regular street-legal car will ever be able to brake. Furthermore, the hydraulic circuits for the brakes front and rear separated, to prevent all of the brake pressure, for example, by technical malheur to one wheel.
Still a few loose facts in your mind:
- The Brembo discs of an F1 car weighing 1.2 kg and measuring 278 mm. The carbon/ceramic copies on a Ferrari FF measure 398 mm and weighing 6.7 kg.
- F1-brakes go for about 800 km, at 300,000 km for which of the FF.
- The discs of an F1 car are more than 1,000 small openings to the quantity of cooling.
- Calipers roads in the F1 between 1.5 and 2 kg. In a street-legal car runs this weight up to 5 kg.
- Conversely, straatexemplaren over half a million miles to go, at 10,000 km for F1 clutches.
