Why brake dust is a big problem in 2022

(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 always fell on their faces whereas driving, and that it was dangerous to their well being.

Sebastian Vettel in explicit raised the problem 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 12 months 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 simple 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 by the wheels.

As a end result, an try was made to centralize the airflow by introducing a necessary rear-facing airflow. However, this appears to have triggered the carbon dust problem.

Stricter guidelines

Under earlier rules, groups directed not solely airflow, but in addition warmth and brake dust immediately out by the tire tread. This freedom has led to a variety of options centered on the benefits the groups can obtain from an aerodynamic perspective.

This has led not solely to complicated brake effectively designs, however options comparable to blown axles and customized rim designs.

The new rules for 2022 are designed to additional cut back the incidence of spills. This additionally consists of one-piece rims and rim caps, with the outer drum forming a seal in order that airflow can solely enter and exit by the entrance and rear openings.

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 placement of inlets and openings are dictated by the foundations, whereas design groups have some freedom for individuality. However, the rear exhaust might be one facet 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 an alternative of a most of 278 millimeters – so in concept extra dust is emitted.

In addition, the diameter of the drilled cooling holes by the brake disc should now be at the very least 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 elements, brake dust can improve resulting from these radical modifications in the inventive freedom of the staff.

In session with the groups, the small print of the development of the brake discs and pipes are taken into consideration – as a result of it is vital to search out a good resolution with out eliminating the the explanation why the air doesn’t fly out of the automotive.

In the long run, the FIA ​​might contemplate one thing extra radical, comparable to altering the fabric of the discs.
