In order to handle these problems, Brembo provides the teams with a friction material for discs and pads characterised by extremely low wear and by more efficient thermal conductivity. This friction material guarantees optimum warm-up times, in other words, they quickly reach the most efficient operating temperature, and they have a wide range of use, both in terms of pressure and temperature, and a very linear friction response. These are all characteristics that provide the driver with perfect modulation of the braking system.
The incredibly low wear also allows performance to stay unchanged and repeatable from start to finish. The cast iron discs, on the other hand, do not require minimum operating temperatures and are therefore immediately effective even at low temperatures. Nevertheless, cast iron is a particularly sensitive material to thermal stress, so for the cast iron discs the greatest danger is the formation of cracks due to the continuous rise and fall of the disc temperatures in the straight stretches and the hard braking sections.
