Between engines, tires and aerodynamics, In 2026 everything is destined to change and the brakes are no different. The scope of the Power Unit revolution is such as to condition the development of each area of the single -seater, including the braking system. Brembo observes a proliferation of different solutions among teams, also based on the conceptual choices of individual motorists, also recording a spasmodic attention for the weight. FormulaPassion He had the opportunity to deepen the topic with Andrea Algiers, head of F1 customers for Brembo Racing.
The brake is born from the engine

Algiers tells how the 2026 regulations are accompanied by numerous unknowns, giving life to large design differences between the teams: “We obviously refer to the simulations of the teams, which are quite discordant. It is not very clear who is right. Especially on the rear, The teams are making choices directly related to energy recovery strategieswhich are quite different. At the front, the braking is more classic and everyone tries to size the system according to couples and temperatures, while at the rear it depends a lot on the type of power unit that will be made. We have fairly disparate solutions. “
On the basis of how they are designed to work, the power units of the individual motorists follow different logics for battery management. There are several charging strategies, on which the use of regenerative braking in support of the hydraulic system depends. Algiers continues: “In function of these strategies and depending on the conditions, The brake could be very promptly or not very prompt. Obviously we size the brake for the most demanding scenario, but it will be necessary to offer a material that is ready to react even in conditions in which the electric motor will carry out much of the braking work on the rear axle, and then suddenly resort to the discs “.
“We are studying on solutions that will be carried out after the summer for a more or less delivery between the end of November and the early December. Our customers have a fairly clear trend at the front, while at the rear there are some quite evident countercurrent choices. If these teams had guessed the road, all the others should follow laterbecause they are very compact and light solutions. If, on the other hand, they hadn’t hit it, they should be the one to realize most of the group. “
Watch out for temperatures
The charging strategies could be such that in some curves it would curb only through the electric motor. The disc brakes could therefore remain unused for prolonged periods of time, cooling and placing new challenges for the designers. Explains the engineer Brembo: “Carbon needs a certain temperature to work at its best. For this sthey will change changes so that it can be used as any road brakewhich after 50 kilometers on the highway is ready as soon as it is operated. This will be a bit the hot theme of next year “.
“Our material has the particularity of having a good friction even from cold. It will be necessary to understand if further changes will be needed, because a cold ‘from 150-200 ° C is different that from 20 ° C. It will be necessary to study the work cycles of these rear axles. exploit the brakes, which from the ambient temperature reach 800 ° C. In this temperature interval our carbon behaves in an excellent way. We hope that the 2026 scenario will be similar “.
With disk brakes intended to be used in a different way, Brembo is preparing to review the ranking of the most demanding slopes for the braking system: “To date, the heaviest circuits are Canada, Bahrain, Singapore and Monza, but this hierarchy next year could change precisely for this type of approach. There is a lot of talk about Monza, where to recover sufficient energy you will need a peculiar use of the electric motor, deeply changing the exploitation strategy of the brakes. It is likely that we will have to review our circuit ranking a bit. The heaviest ones in 2025 may no longer be in 2026 “.
The news
Everything is part of a technical regulation with numerous changes at the level of the braking system. Explains Algiers: “At the front the size of the discs will be able to grow a lot. The maximum diameter can reach 345 mm, against the current 330 mm, while the thickness will rise from 32 to 34 mm. At the rear instead only the thickness will grow, up to 34 mm, while the maximum diameter will always remain of 280 mm “. Those of 2026 will be theoretically capable of reaching higher speeds on the straight, instead supporting lower travels when cornering. Thus grows the speed leap and the energy to be dissipated during braking, leading to an enlargement of the discs: “The minimum diameter of the ventilation holes on the discs will also change, which will be able to return to a minimum of 2.5 mm, as in the past”.
“Another important novelty is that the caliper can have more than six pistons and reach up to eightwith three points of attack on the door holder instead of the two current ones. This was a constraint that had resisted a couple of decades and opens some doors for the designers, who will be able to indulge themselves a little from this point of view “. It is an opportunity that the teams pondered carefully, guaranteeing certain advantages: “The more fractions the system, the more for the same hydraulic pressure you have a better distribution of the braking force on the tablet against the disc, with a better friction yield”.
Fight against weight
It is not so obvious that the teams will take the opportunities of the regulation in terms of sizing the discs and number of pistons. The engineers, in fact, agrees in saying that reaching the minimum weight will be extremely challenging in 2026 and Brembo witnesses it: “The increase in the maximum diameter of the discs is so large as to also cause an important aggravation of weight not only for the disc, but also for the caliper that is around us. From what we are seeing, practically nobody is developing to the maximum size as it happened in the past”.
“In 2026 the search for the minimum weight will be spasmodic. Everyone is trying to have a sufficiently performance system from the point of view of couples and cooling, but at the same time as light as possible. With the diameter of the discs you will not go beyond 330-335 mm in diameter, while being able to reach 345 mm from the regulation. Let’s see truly extreme solutions from the point of view of weight saving “concludes Algiers.
