Brake expert Brembo has unveiled a new family of aluminum fixed calipers for high-end vehicles at the 2015 International Motor Show in Frankfurt. These new calipers are available in three versions: 17 inches (5.9 kg), 18 inches (7.7 kg) and 19 inches (8 kg) – all providing a lightweight solution for vehicles with a high braking disc surface.
Such discs typically need larger yet heavier calipers. But with Brembo’s new aluminum calipers, an increase in size does not necessarily mean a large surge in weight. Brembo’s new fixed caliper features a size just right for discs with high braking surfaces, but with incredible lightness.
Interestingly, Brembo has been developing this lightweight brake since late 2011 and has invested over 100,000 development hours. Production of the brakes has been commenced just recently.
The brakes features a unique shape centered on five openings -- two at the front, between 16 sq. cm. and 22 sq. cm, and three on the bridges, with an area between 7 sq. cm and 11 sq. cm.
This allowed Brembo to cut the mass of the caliper by almost eight percent. Brembo also managed to achieve additional mass savings in material at the points with the lowest stress. With this reduction in the unsprung mass of the vehicle, owners can expect lower fuel consumption and emissions.
This Brembo-patented design enables the calipers to be light without sacrificing stiffness and performance. Despite the five openings in the brake, the design has not resulted to any worsening of performance in the braking system.
During the development process, the brake-makers paid special attention to the aesthetics of the new family of aluminum calipers. Brembo – in cooperation with their OEM customers -- is planning to implement solutions that will be tailored to individual vehicle models as each carmaker has their own design styles.
Based in Curno, Italy, Brembo S.p.A. develops and manufactures braking systems for vehicles. The company is the supplier to several major manufacturers of cars, commercial vehicles and motorbikes around the world.
With operations in 16 countries, Brembo has 24 production and business sites and around 7,700 employees. Around 10 percent of the company’s workforce is involved in R&D, including engineers and product specialists.
