Six options of carbon discs
The cars’ aerodynamic set-up defined for 2020 is similar to the one launched in 2019, with a simplified front wing to reduce downforce that means an increase in vehicle speed and consequently more braking efforts.
The cars go faster on the straights, but have less grip, which reduces the braking torque on the ground. This leads the driver to hit the brake pedal sooner, increasing the energy that needs to be dissipated mainly through heat.
Brembo has developed new carbon discs using specific ventilation technologies to manage greater thermal stress.
The majority of the cars will use
front discs with 32 mm thickness and rear discs with 28 mm. Depending on the temperatures expected during a Grand Prix and the specific race strategy,
each driver can choose between six different options of Brembo discs.
In 2020 are confirmed
three disc solutions for the
front braking system:
• the 1480 holes disc is the most extreme solution, called "Very High Cooling" arranged on 7 rows
1250 holes disc solution called "High Cooling" arranged on 6 rows
800 holes disc solution called "Medium Cooling" arranged on 4 rows
each specification is also presented with a process on the external diameter, that is called "groove". The new family discs with "groove" is characterized by processing on the outer diameter of the disc which creates a section diverging from the air and which in turn comes out of the disc's ventilation holes. This geometry allows for greater material cooling efficiency.
rear braking system, are confirmed
two disc solutions:
1250 holes disc solution called "High Cooling" arranged on 5 rows
800 holes disc solution called "Medium Cooling" arranged on 3 rows
The result is
a total of six different ventilation specifications only for the front axle and two different ventilation specifications for the rear axle.
The secret behind this technology is here, the solution of 7 rows with “groove” to make it suitable for the most severe circuits, such as Sakhir's in Bahrain, Marina Bay's in Singapore, Montreal’s in Canada and Yas Marina’s in Abu Dhabi.
In tracks like these, the temperature of the discs can reach peaks of up to 1,200 degrees.
