As rules change and evolve, F1 groups discover themselves capable of finding new methods to reincorporate good ideas that labored beforehand however out of the blue misplaced their edge for one purpose or one other.
The newest instance of this phenomenon is the reintroduction of grooves on the brake disc rotor, with Carbone Industries trialling them at current races.
Williams carried out some experiments on the Italian Grand Prix, with Alpine additionally becoming a member of the motion in Mexico.
Whereas the hope is all the time of tweaks like this including some direct instantaneous efficiency benefits for this 12 months, it’s extra doubtless that the designs are targeted on subject testing options in preparation for 2025.
This early sighter may even enable the groups equipped by the French producer, which is over half the grid, ample time to organize and optimise the remainder of the braking system and brake duct design round tailor-made new options from the brake disc provider.
The variations that might drive totally different performances from the grooves each now and sooner or later embrace the variety of grooves, their size, form and depth.
F1’s swap from 13-inch to 18-inch tyres has resulted in groups having to enlarge the scale of the brake drum to match the revised wheel nicely dimension.
This requirement has been additional ramped up as there have been additionally adjustments made to stop the drum and wheels from getting used to expel warmth and air that might present an aerodynamic contribution to growing outwash.
This has resulted in quite a few new options arising to assist transfer warmth and air across the meeting. Each work to supply the required help to chill elements and switch warmth into the tyre through the wheel rim in a approach that helps handle tyre temperatures.
The obvious of those design options is the disc fairing (as seen above on the Crimson Bull), which has gone by means of numerous iterations because the rules have been launched.
In the meantime, there’s additionally a substantial variance within the design of every brake drum meeting, with groups making a layered nest throughout the meeting to assist direct the air and warmth earlier than making use of the outer brake drum, which should now be sealed to stop any secondary aerodynamic results from being employed.

The first purpose for the reintroduction of grooves on the discs although, which is one thing we final noticed when groups used metal discs, is more likely to do with growing the preliminary chew that is created when the brakes are utilized.
It will have a double profit when it comes to altering the method from the motive force, and maybe making him really feel extra comfy, but additionally how warmth is transferred by means of the meeting.
Ought to these current trials have proved profitable, and others start to undertake grooved discs, there’s additionally a big probability we’ll see additional alterations made to the remainder of the brake meeting too.
To not be outdone, Brembo and the groups equipped by them may have additionally taken observe of those trials and can doubtless be taking a look at the way it can implement any potential positive aspects from grooved brake discs for 2025 and past.
