Why brake dust is such a big problem in 2022

(Motorsport-Total.com) – The FIA ​​will need to discuss to groups in the approaching weeks about whether or not motion is wanted to take care of the brake dust problem. Drivers complained that they consistently hit their faces whereas driving and inhale brake dust, which might result in well being issues.

Sebastian Vettel in explicit raised the difficulty after the race in Austria when he turned as much as the interview spherical with a dusty face. “To be sincere it is one thing they should work on as a result of the entrance brake duct design is blowing all of the brake dust in our faces this 12 months and that is not a good factor,” he mentioned.

“Inhaling carbon dust is not precisely wholesome. I hope the FIA ​​will look into it very quickly as a result of it is pointless and straightforward to alter.”

Rules for 2022 relating to brake duct design have been modified to restrict the flexibility for groups to create an aerodynamic washout by blowing air via the wheels.

As a consequence, makes an attempt had been made to centralize airflow with the introduction of obligatory rear-facing air vents. However, it seems to have precipitated a carbon dust problem.

Strict guidelines

Under the earlier guidelines, groups performed not solely airflow, but additionally warmth and brake dust straight outward via the wheel treads. This freedom led to a sequence of options that centered closely on the advantages groups might obtain from an aerodynamic perspective.

This led not solely to advanced brake effectively designs, but additionally options such as blown axles and bespoke rim designs.

The new guidelines for 2022 are designed to additional scale back washout era. These additionally embrace unitary rims and rim covers, with the outer drum forming a seal in order that airflow can solely enter and exit via the entrance and rear openings.

Teams nonetheless have some leeway in how they’ll creatively handle the warmth and airflow contained in the brake drums. Most groups have opted for a fairing that surrounds the brake disc, just like the Red Bull RB18.

Is the FIA ​​altering the rear shops?

The form, dimension and place of inlets and shops are specified in the principles, with design groups having some leeway for individuality. However, the rear exhaust could also be one side of the design that the FIA ​​is seeking to change in the trail of brake dust, maybe giving groups an excessive amount of leeway at this early stage of the principles cycle.

It must also be remembered that the diameter of the brake disc has elevated considerably for 2022: it is now between 325 and 330 millimeters as a substitute of the utmost 278 millimeters – so in concept there is extra dust to get out.

In addition, the diameter of the drilled cooling holes passing via the brake discs should now be a minimum of three millimeters, which dramatically impacts the quantity and design of the holes used. The guidelines now additionally specify that no cooling openings are allowed in the brake pads.

In the sum of those elements, it could be that break dust rises resulting from these basic modifications in the workforce’s inventive freedom.

In session with the groups, the main points of the development of the brake discs and ducts shall be taken into consideration – as a result of it is vital to seek out a good resolution with out destroying the the reason why the air doesn’t blow out of the automotive.

In the long run, it is attainable that the FIA ​​might contemplate one thing extra radical, such as altering the fabric of the disc.
