The FIA has updated the Formula 1 technical regulations during the summer break to outlaw the use of asymmetric braking systems.
Speculation linked Red Bull, to the use of such a system, which would allow for uneven levels of braking on either side of the rear axle.
The theory behind employing asymmetric braking systems was to combat understeer, a particular pitfall of the current ground effect regulations.
With ground effect F1 cars prone to understeer in slow corners, disproportionate cracking could in theory promote better steering through the turns
In light of this, Article 11.1.2 of the F1 technical regulations now reads: “Any system or mechanism that can structurally or intentionally produce asymmetric braking for any axle is prohibited.”
The changes to the regulations were approved by the World Motor Sport Council on July 31, two days after the conclusion of the Belgian Grand Prix, making F1’s trip to Zandvoort the first race meeting in which the amended 11.1.2 article will be prevalent.
The aforementioned text in the regulations follows the original element of Article 11.1.2 which read: “The brake system must be designed so that within each circuit, the forces applied to the brake pads are the same magnitude and act as opposing pairs on a given brake disc.”
Speculation across the internet and social media hinted toward Red Bull’s downturn in form post-Miami GP to be linked with the alleged banning of a braking system, with more accusations linking such a system to Verstappen’s brake failure at Melbourne.
Red Bull has denied any such claims, however, and the FIA has also sought to clarify the amended Technical Regulations are not related to any systems being run by any of the teams.
“There is no truth that any team was using such a system,” a member of the governing body told Motorsport.com.
In fact, according to Motorsport.com‘s report, the FIA has claimed the original wording of Article 11.1.2 prohibited the use of any sort of asymmetric braking system.
Instead, the theory behind the amendment is to clarify in clearer terms what is and isn’t allowed within the regulations which is just as well given the tendency for F1 engineers and designers to exploit loopholes.
In summary, this is merely a future-proofing exercise with the FIA determined to solidify the parameters of the technical regs not just in the present moment, but for next season and more importantly, 2026 – where a major shakeup will see teams navigating a radical change in F1 design.
