THE BREMBO FORMULA E BRAKING SYSTEM
All the Formula E single-seaters are equipped with the same complete Brembo bespoke braking system: calipers, carbon discs and pads, bells and tandem pump.
The discs are carbon made, specifically designed for the needs of full electric cars.
Front: Thickness of 24 mm, diameter 278x24 mm, ventilated disk with 70 holes (diameter of single hole of 6.2 mm);
Rear: Thickness of 20 mm, diameter 263x20 mm, ventilated disk with 90 holes (diameter of the single hole of 4.2 mm).
The monoblock machined 4-piston caliper is made of an oxidized aluminum alloy and weighs less than 1 kg at the rear (with piston diameter of 26-28 mm) and about 1.2 kg at the front (with piston diameter 30-36 mm).
The design of the caliper has been pushed to the limit: it has been considerably lightened in the less stressed areas in order to maximize weight reduction without compromising its stiffness. This has led to a dynamic and sporty aesthetic identity, in line with the features of the cars that equips.
The pads are carbon made: the front ones are 18 mm thick, while the rear ones are 16 mm. The bell is made of aluminum with bobbin mounting. The system is completed by the tandem master cylinder.
In terms of temperatures, the data measured at the very beginning of the braking action have shown that the discs can reach temperatures of 400-500 degrees, with peaks of 800 degrees in the most rough situations.
Brembo Formula E brakes have been developed considering the main challenge represented by the design of competition braking systems: by their very nature they must always represent the best possible balance between performance, safety, lightweight, durability, constant efficiency and low costs.
