Brake Pressure Increase Restriction

In Simple Terms

F1 teams cannot artificially boost the brake pressure beyond what the driver's foot applies to the pedal, with one exception: the rear brake system is allowed to increase pressure automatically. This ensures the driver has direct control over braking while allowing engineers to optimize rear brake performance.

• Brake caliper pressure must be limited to what the driver physically applies through pedal force
• The rear brake control system is the only exception and may increase pressure beyond driver input
• This rule maintains driver control and safety by preventing unwanted pressure amplification in brake systems
• Applies to all brake calipers except those controlled by the rear brake system
