Brake Calliper Pistons

Chapter: C11

In Simple Terms

Each wheel in an F1 car must have one brake calliper (the device that grips the brake disc) with a minimum of 2 pistons and a maximum of 8 pistons working in opposing pairs. This regulation ensures teams have standardized braking systems while allowing some flexibility in design.

  • One calliper per wheel is mandatory
  • Minimum 1 pair of opposing pistons (2 pistons) required
  • Maximum 4 pairs of opposing pistons (8 pistons) allowed
  • Opposing pistons work together to clamp the brake disc from both sides
