Brake Disc Thickness

In Simple Terms

F1 brake discs cannot be thicker than 34mm. This maximum thickness limit ensures all teams use similar brake technology and prevents unfair advantages through larger disc designs. Thicker discs could dissipate heat better, giving some teams an unfair performance edge.

• Maximum brake disc thickness is strictly limited to 34mm
• This regulation applies to all teams equally to maintain competitive balance
• Thicker discs would provide better heat dissipation and performance advantages
• Teams must submit brake specifications for technical approval before races
