The weights of a Brembo Formula 1 system
Just as with all the other components in single-seater cars, the essential characteristics for the braking system are weight, durability and guaranteed performance. As it's unsprung weight, fuel consumption drops and the car's grip and handling improve when the weight is decreased.
Unlike the braking system in a road car, which weighs about 20 kg (44 lb) per wheel, the Brembo Formula 1 system weighs about 5 kg (11 lb): the carbon disc makes up a quarter of the weight (1-1.25 kg or 2.2 to 2.75 lb), whereas the aluminum/lithium caliper is heavier, ranging from 1.5 to 2 kg (3.3 to 4.4 lb). On the other hand, the F1 carbon pad weighs 200 grams (7 ounces).
