What are F1 brake discs made of?
Table of Contents
carbon fibre
The brake disks of Formula 1 cars are made of a composite material reinforced with carbon fibre. The coefficient of friction between the pads and the discs can be as much as 0.6 when the brakes are up to temperature. Steel brake disks would exhibit a higher wear rate at these high temperatures.
What materials are used to make brake discs?
Cast iron and carbon are the two main materials used to make a brake disc. The benefit of Carbon is that it has a high thermal resistance and is lightweight. The downside is that Carbon is expensive, so it is used mainly by high budget racing teams. Cast iron is the more commonly used base material.
What metal are F1 brakes made of?

Everything depends on the bite of the brakes on the discs, so F1 cars run carbon discs and pads with aluminium six pot calipers. Carbon fibre is used for two main reasons and it’s not the myth about steel brakes being less powerful.
What is the best material for brake disc?
Cast iron
Cast iron is a common material for automobile brake discs. Many researchers have pointed out that vermicular graphite cast iron has relatively good friction and wear performances. Additionally, it is used as the base materials for brake discs in most automobiles.
Are F1 brakes carbon ceramic?
The carbon-ceramic brake discs are derived directly from the carbon models used in Formula 1, used exclusively while on track due to relatively high minimum operating temperatures, but can also be used for standard road vehicles due to their effectiveness even when “cold”.

What steel is used for brake discs?
martensitic stainless steel
A material for a brake disc of a two-wheeled vehicle, etc., is required to have properties such as abrasion resistance, rusting resistance and toughness and a JIS SUS410 type martensitic stainless steel has been mainly used for such applications.
Why is cast iron used in brake discs?
Grey cast iron contains carbon flakes which produces the most effective noise dampening properties of all irons and steel. It also enables high thermal conductivity properties making it the first choice for braking.
Who supplies F1 brakes?
Brembo
Brembo has been the largest brake supplier in Formula 1 for many years. Currently, the Italian manufacturer supplies the brakes to eight F1 teams. The brake manufacturer is also active in other racing classes and from the experience gained in those classes they developed the new T3 brake disc.
Why do F1 brakes smoke?
In F1 ,Brakes tend to reach extreme temperatures . So the only way to cool them is from the air that’s passing through it . Which will happen when the car is moving or when the mechanics apply induced cooling with a fan at the pits. So when stationary the cooling of the brakes is significantly low and thus the smoking.
What metal is used in brakes?
Semi-metallic brake pads are made up of metal shavings: copper, steel, brass (and maybe some graphite thrown in) and bonded with resin. They are best suited for heavy-duty or performance use, although they can also be applied to daily driving. Semi-metallic brake pads have the greatest amount of stopping power.
