BREMBO FURTHER DEVELOPS BRAKING SYSTEMS FOR FORMULA ONE WORLD CHAMPIONSHIP
March 18, 2016 by BremboThe Italian company has focused on the supply of lighter, more compact braking systems and with optimized performance in terms of cooling and resistance to stress DETROIT, (Mar. 17, 2016) - With an involvement in Formula One beginning in 1975, Brembo reasserts its technological leadership in the maximum premier motorsport series by equipping with its braking systems the most important teams taking part in the 2016 Championship. Brembo supports the work of each team bringing technological innovation, maximum reliability and integrated solutions and focusing on the refinement work of the individual elements composing braking systems, now lighter, more compact and able to ensure further improvement in terms of performance. From the regulations point of view, the 2016 Formula One season does not present significant changes compared to 2015, in view of the important technical developments expected in 2017, when the Italian company will be ready for a new technological challenge, with more performing F1 cars able to develop greater braking torque. For this reason, much work has already been done during the winter by Brembo technicians to make the brake discs much more efficient and resistant thanks to increased thickness (from current 28mm to 32mm in 2017), with a consequent further adaptation of braking cooling system and the possibility to contemplate a greater number of ventilation holes compared to over current 1,200. Formula One demands an extensive customization of brake systems deriving from the different solutions adopted by F1 car designers. Each team supplied by Brembo requires a brake system that is increasingly 'tailor-made', closely integrated with the design of the car and certain to undergo continuous development during the course of the season. As regards brake calipers, for example, the perfect integration of the component with cooling system of corner (air duct, drum, and deflectors) and with the aerodynamic solutions studied by each team, ensures that each component is different for each team and unique. Furthermore, different are the choices related to the maximum research of stiffness, or the lowest possible weight, often decided according to the preferences of drivers. In addition to the design of braking system, Brembo continues the development work of the individual components of the Brake By Wire (BBW) system. The engineers further broadened their skills in order to produce a variety of different BBW components in response to the requisites of each individual team and further working on the assembly of the parts within the system and the miniaturizing of the components themselves. For certain teams, Brembo developed only some BBW components, for others the Company conducted more extensive work concerning the entire BBW circuit: from the simulator on which operates the rear brake master cylinder, to the actuator controlled by the control unit and which drives calipers on the rear axle, to the safety valves system that controls the switching.

In recent years, Brembo brake discs ventilation has undergone a constant change, considerably increasing the absolute performance of braking system. The optimization work carried out on cooling system of brake discs, which can reach in Formula One a maximum temperature of more than 1,000°C (1,832°F), along with the extremism of the design of ventilation holes, increased in number (currently more than 1,200 for each disc), has resulted in a huge modeling and simulation work to always ensure the structural resistance even with such extreme processing work. This design evolution has required the development of a specific process for the mechanical processing which requires the maximum precision on extremely lowered diameter holes. Significant decrease in the brake system wear level with CER During the winter, technicians worked on carbon brake disc material to improve performance continuity and operating range. CER has considerably reduced 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 and temperature, together with very linear friction characteristics. All of these features contribute to giving the driver extremely precise control over the braking system. Furthermore, the incredibly low wear rate of this material ensures consistent, repeatable performance from the start of the race to the checkered flag. For the 2016 season, all teams equipped by Brembo will use the same CER 300 brake disc material, while the Company continues its research in this field to produce composite materials that continue to offer more performance and controllability. Geometries of ventilation discs are instead deeply customized to adapt to each individual team. Track mileage recommended by Brembo for the use of brake discs, due to the extreme design now reached, is 800 km (497 miles) in optimal temperature conditions. All teams are equipped with ventilated CCR 700 brake pads, with up to 80 ventilation holes for each pad. Ventilation holes are customized in response to the requirements of each team. Key facts and figures In a complete season, on average Brembo supplies the following materials to each team running two race cars: ◾10 sets of calipers ◾From 140 to 240 discs ◾From 280 to 480 brake pads The manufacture of each of brake calipers in aluminum/lithium requires over 14 hours of consecutive machining to achieve the perfect balance between weight and stiffness. Brembo recommends the revision of brake calipers after 2,500 km (1,553 miles) of normal use. Production and mechanical process of a brake disc require nine months. Brembo Racing structure includes more than 100 technical specialists for the various stages of simulation, calculation, design, engineering and testing. A staff of race engineers is available for the teams for all tests and races activities.
