(Motorsport-Total.com) – The FIA needs to speak to groups in the approaching weeks about whether or not measures are wanted to take care of brake dust. Drivers complained that brake dust continually 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 problem when he got here to the dusty interview stage 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 12 months and that is not a good factor,” he stated.
“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 relating to brake duct design had been modified for 2022 to restrict the flexibility of groups to create an aerodynamic wash by blowing air via the wheels.
As a end result, an try was made to centralize the airflow by introducing a obligatory rear-facing airflow. However, this appears to have brought about the carbon dust problem.
Under earlier rules, groups directed not solely airflow, but in addition warmth and brake dust immediately out via the tire tread. This freedom has led to a variety of options specializing in the benefits that groups can obtain from an aerodynamic viewpoint.
This has led not solely to complicated brake properly designs, however options comparable to blown axles and customized rim designs.

This is what the Red Bull RB18 brakes appear like scaling
The new rules for 2022 are designed to additional scale back the prevalence of spills. This additionally consists of one-piece rims and rim caps, with the outer drum forming a seal so airflow can solely enter and exit via the entrance and rear vents.
Teams nonetheless have some leeway in how they’ll 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 site of inlets and openings are dictated by the principles, whereas design groups have some freedom for individuality. However, the rear exhaust might be one side of the design that the FIA is contemplating to vary the brake dust path, presumably giving groups an excessive amount of leeway at this early stage of the rules cycle.
It must also be remembered that the diameter of the brake discs has elevated considerably till 2022: it is now from 325 to 330 millimeters as a substitute of a most of 278 millimeters – so in idea extra dust is emitted.

This 12 months, the dimensions of the brake is bigger scaling
In addition, the diameter of the drilled cooling holes via the brake disc should now be no less than three millimeters, which dramatically impacts the quantity and design of the holes used. The guidelines additionally make it clear that cooling vents are not allowed in brake pads.
In mixture with these elements, brake dust can improve as a consequence of these radical adjustments in the artistic freedom of the workforce.
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 necessary to search out a good resolution with out eliminating the the reason why the air doesn’t fly out of the automobile.
In the long run, the FIA could think about one thing extra radical, comparable to altering the fabric of the discs.
