Calliper Piston Section

In Simple Terms

F1 brake calipers must have pistons with circular cross-sections. This ensures consistent braking performance and prevents unfair advantages from unconventional piston designs.

• Brake calliper pistons must have a circular cross-section (not oval, square, or other shapes)
• This requirement applies to every piston in the braking system
• Circular pistons provide uniform pressure distribution for predictable braking
• The rule prevents teams from gaining performance advantages through non-standard piston geometry
