Although the brakes are the most powerful part of an F1 car and they are made of high-end carbon composite, they still are subject to certain limits. Their ruthless enemy being especially the incredible temperatures they have to cope with. The brake disc temperature remains 400 - 800°C and exceedes 1000°C in certain situations. The braking clamps, made of composite or aluminium alloy ask for temperatures around 200 - 250°C. To prevent exceeding such temperature limits, which ensure the brakes' full function and supposed wear, they must be cooled down effectively. The brakes are cooled by ram air lead in by a light composite duct. This part of mere 100g of weight sticks to the through-flow pitman of the wheel and the clamps. Its size is specified by FIA regulations so that the teams might not gain any advantage by altering the shape and consequently efficiency of the brakes.
