F1 TECHNOLOGICAL CHALLENGE RESTARTS WITH SEVEN TEAMSGreater Proportion of Braking Force in Front, Smaller Rear Discs andBrake By Wire System in 2014 Formula One World Championship
STEZZANO, Italy, March 14, 2014 – Participants in Formula One since 1975 resulting in 23Constructors and 19 Drivers World Championships, Brembo reaffirms its leadership status in 2014as supplier of braking systems to seven teams involved in F1: Caterham F1 Team, Infiniti Red BullRacing, Mercedes AMG Petronas F1 Team, Sahara Force India F1 Team, Sauber F1 Team, ScuderiaFerrari and Scuderia Toro Rosso.
Based on new FIA regulations adopted for the 2014 season, several important technicaldevelopments (smaller, more fuel-efficient engine, increase in the minimum weight to 691 kg, andthe reduction of downforce) will obviously have a significant impact on the F1 braking systems,
including the new callipers and carbon friction materials.
For 2014, a greater proportion of braking force will be transferred to the front axle with themaximum brake torque ideally decreasing due to the reduction of downforce and speed of thecars. Stopping distance, on the contrary, will be greater and, consequently, time spent underbraking increasing.
For these same reasons, rear brake discs can be smaller in diameter compared to last season, witha resulting advantage in terms of weight and speed of response to pressure. Their thickness may
also be thinner (25mm), due to the reduction of the energy to dissipate.
In 2014, the new Energy Recovery System (ERS) creates increased drag on the car under braking
and therefore requires electronic control of the rear brake pressure to insure chassis stability. To
accomplish this, an innovative system has been incorporated: Brake By Wire (BBW). As the driver
brakes, the BBW electronic controller provides the high-pressure hydraulic system with the proper
braking force to the rear axle. In case of emergency, the master cylinder remains connected to thebrake pedal and the hydraulic connection directly to the calipers for the driver to operate, but thisfunctions only in case of a BBW failure.
Brembo has been active in the design and simulation of BBW braking systems, as well as theindividual components of Brake By Wire. For some teams, the Italian company has developed only
the actuator, which acts as an interface between the hydraulics of the car and the rear calipers. For
other teams, Brembo has developed a more substantial part of the BBW system, involving thevalves that influence the BBW switch from normal use to emergency condition.
Greater ventilation for brake discs
In recent years, Brembo engineers have completely changed the brake cooling, which in F1 canreach a maximum temperature of 1.200 °C, by redesigning the cooling system to include up to
1,000 ventilation holes. The ventilation of Brembo carbon brake discs went through adevelopment process resulting in a considerable increase in overall performance of the braking
system.

The increase of airflow was also achieved through CFD calculations (Computational FluidDynamics, fluid dynamics study through computer), a synergic study, developed by each race
team, of the airflow between the intake and the brake disc. This resulted in an optimal design ofventilation holes, which increased in number but reduced in diameter, thereby increasing
exponentially the carbon surface open to airflow and therefore thermal discharge. This structural
evolution required a much more complex mechanical processing, along with a growing effort interms of in-depth analysis of fluid dynamics. The support of each team has been crucial to thedesign of air intakes for new cars.
Lower wear of brake system thanks to CER and customization of systems
Material is considerably changed as well. CER represents an evolution of CCR material thatconsiderably reduces wear, guaranteeing more effective thermal conductivity. Compared toprevious material, CER offers excellent warm-up time; that is, maximum rapidity in reaching more
efficient operating temperatures; a wide application range in terms of both pressure andtemperature, and very smooth friction performance. All these features provide the driver with aperfect modulation of the braking system. The incredibly low wear results in more reliable
performance from the start to the end of race. Disc material is the same for all teams supplied byBrembo, who continues to research and develop composite materials that are more manageable.
Significant numbers
In a full season, Brembo supplies each team with the following material for its two cars:
 10 sets of calipers (i.e. 4 x 10 components)
 From 140 to 240 discs
 From 280 to 480 pads
Some ten hours of continuous manufacturing activity are required to produce a caliper, although
in reality the process is interrupted by other steps including various surface treatments, handassembly and subsequent testing. Both the materials and the steps of the entire process arealways 100% tested.
