BREMBO CONFIRMS ITS COMMITMENT TO THE WORLD'S PREMIER
RACING SERIES AS IT CELEBRATES 40 YEARS IN FORMULA ONE
The Brake By Wire (BBW) system, optimised braking system cooling, innovative
brake calipers and advanced in disc technology are just some of the mostsignificant new developments to be introduced for the 2015 season
With an involvement in Formula One beginning in 1975, Brembo - the world's number one producer ofadvanced braking technology and high performance braking systems - celebrates its 40th anniversary in theworld's premier motorsports series and reasserts its technological leadership by equipping the mostimportant teams with its braking systems for the 2015 season, for example: Infiniti Red Bull Racing andScuderia Ferrari.
Following the significant changes in regulations introduced in 2014, which revolutionised braking systems
with the introduction of Brake By Wire (BBW) technology, the 2015 season ushers in yet another evolution inassisted braking, alongside major improvements to further optimise brake system cooling. The teams
equipped by Brembo will be using new more efficient brake calipers which benefit from a better integration
into the wheel corner - a factor which also contributes to improving the overall aerodynamic performance ofthe race car. The manufacture of each of these new brake calipers in aluminium/lithium requires over 14hours of consecutive machining to achieve the perfect balance between weight and stiffness.
Brembo was responsible for the design, simulation and engineering of the brake system as a whole and of
the individual components of the Brake By Wire system. With the benefit of 40 years of experience in racing
and the Italian company's continuous commitment to investing in research and development, Brembo's
engineers further broadened their skills in order to develop and produce a variety of different BBW
components in response to the requisites of each individual team. In addition to this, the engineers also
worked to optimise the assembly of the parts within the system and to further miniaturise the components
themselves. For certain teams, Brembo developed the actuator only, which acts as an interface between thehydraulic system of the race car and the rear calipers. For other teams, Brembo conducted more extensive
projects encompassing a substantial portion of the BBW circuit, such as the valves switching the Brake By
Wire system between normal and emergency operating state and the simulator recreating the sense of
stiffness in the rear circuit to provide the driver with adequate brake pedal feedback.
In 2014, the brake balance was shifted even more towards the front wheels, while as the year progressed,
maximum braking torque increased by 15%. This increase in braking torque was the result of continuousdevelopments in aerodynamics, which increased the amount of available grip.
Even more effective brake disc ventilation
In recent years, Brembo's engineers have continuously improved brake disc cooling - as in Formula One, thediscs can reach temperatures of up to 1200°C - by increasing the number of ventilation holes (with up to1200 holes in some cases) and optimising the fastener system between the disc and the hat to increase
structural strength. Increasing the number of holes in the disc can only improve cooling performance if themass flow through the holes is sufficient to ensure an efficient heat exchange, and this was ensured throughadvanced CFD (Computational Fluid Dynamics) analyses and a synergistic optimization process with eachindividual team in the design of their specific brake duct for their specific car. The discs now have morenumerous, smaller ventilation holes, exponentially increasing the area of the carbon surface in contact withthe air flow and, as a consequence, the ability of the disc to dissipate heat.
The structural evolution not only called for a much more complex and delicate machining process, but also
for a more extensive understanding of fluid dynamics theory. The contribution of the engineers of eachindividual team was crucial in optimising the air intakes of the new race cars for these discs.

Less brake system wear with CER
Even the material from which the discs are made has changed radically. The CER carbon brake disc material
significantly reduces wear while ensuring more effective heat conduction, reducing the warm up time needed
to reach operating temperature, and offering a broader operating range in terms of both pressure andtemperature, together with very linear friction characteristics. All of these attributes contribute to giving thedriver extremely precise control over the braking system.
Furthermore, the incredibly low wear rate of this material ensures consistent, repeatable performance fromthe start of the race to the chequered flag.
For the 2015 season, all teams equipped by Brembo will use the same CER 300 disc material, while Brembo
continues its research in this field to produce composite materials that continue to offer more performanceand controllability.
All teams are equipped with new ventilated CCR 700 brake pads.
Key facts and figures
In a complete season, on average Brembo supplies the following materials to each team running 2 race cars:• 10 sets of calipers• From 140 to 240 discs• From 280 to 480 brake pads
