(Motorsport-Total.com) – The FIA desires to speak to groups in the approaching weeks about whether or not measures are wanted to cope with brake dust. Drivers complained that brake dust always fell on their faces whereas driving, and that it was dangerous to their well being.

Income and expenditure on the brake are strictly indicated in 2022
Sebastian Vettel in explicit raised the difficulty when the dust settled in the interview spherical after the race in Austria. “Honestly, it is one thing they should work on as a result of the entrance brake pipe design is blowing all of the brake dust in our faces this yr and that is not a good factor,” he mentioned.
“Inhaling carbon dust is not dangerous to well being. I hope the FIA will look into it quickly as a result of it is pointless and straightforward to vary.”
The guidelines concerning brake duct design had been modified for 2022 to restrict the flexibility of groups to create an aerodynamic wash by blowing air by means of the wheels.
As a outcome, an try was made to centralize the airflow by introducing a obligatory rear-facing airflow. However, this appears to have precipitated the carbon dust problem.
Under earlier laws, groups directed not solely airflow, but in addition warmth and brake dust straight out by means of the tire tread. This freedom has led to a variety of options specializing in the benefits that groups can obtain from an aerodynamic perspective.
This has led not solely to advanced brake effectively designs, however options akin to blown axles and customized rim designs.

This is what the Red Bull RB18 brakes seem like scaling
The new laws for 2022 are designed to additional cut back the prevalence of spills. This additionally contains one-piece rims and rim caps, with the outer drum forming a seal so airflow can solely enter and exit by means of the entrance and rear vents.
Teams nonetheless have some leeway in how they will creatively handle the warmth and airflow contained in the brake drum. Most of the groups opted for a rim that surrounds the brake disc, just like the Red Bull RB18.
Will the FIA change the rear sockets?
The form, dimension, and placement of inlets and openings are dictated by the foundations, whereas design groups have some freedom for individuality. However, the rear exhaust could possibly be one facet of the design that the FIA is contemplating to vary the brake dust path, probably giving groups an excessive amount of leeway at this early stage of the laws cycle.
It also needs to be remembered that the diameter of the brake discs has elevated considerably till 2022: it is now from 325 to 330 millimeters as an alternative of a most of 278 millimeters – so in concept extra dust is emitted.

This yr, the dimensions of the brake is bigger scaling
In addition, the diameter of the drilled cooling holes by means of the brake disc should now be a minimum of three millimeters, which dramatically impacts the quantity and design of the holes used. The guidelines additionally make it clear that cooling vents are now not allowed in brake pads.
In mixture with these components, brake dust can improve as a result of these radical adjustments in the artistic freedom of the staff.
In session with the groups, the main points of the development of the brake discs and pipes are taken under consideration – as a result of it is essential to seek out a good answer with out eliminating the the reason why the air doesn’t fly out of the automobile.
In the long run, the FIA might think about one thing extra radical, akin to altering the fabric of the discs.
