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 cope with brake dust. Drivers complained that brake dust consistently falls on their faces whereas driving, which is dangerous to their well being.

Income and expenditure on the brake are strictly indicated in 2022


Sebastian Vettel in explicit raised the difficulty in the course of the dusty interview session 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 straightforward to alter.”

The guidelines relating to brake duct design have been modified for 2022 to restrict the power of groups to create an aerodynamic wash by blowing air by means of the wheels.

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

Stricter guidelines

Under earlier laws, groups directed not solely airflow, but additionally warmth and brake dust straight out by means of the tire tread. This freedom has led to a sequence of options that concentrate on the benefits that groups can obtain from an aerodynamic viewpoint.

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

The new laws for 2022 are designed to additional scale 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 means of 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 site of inlets and openings are dictated by the principles, whereas design groups have some freedom for individuality. However, the rear exhaust may very well be one side of the design that the FIA ​​is contemplating to alter the brake dust path, probably giving groups an excessive amount of leeway at this early stage of the laws 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 principle extra dust is emitted.

In addition, the diameter of the drilled cooling holes by means of 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 components, brake dust can improve on account of these radical adjustments in the inventive freedom of the staff.

In session with the groups, the main points 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 explanation why the air doesn’t fly out of the automotive.

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