Brake Disc Diameters

In Simple Terms

F1 brake discs have strict size limits to ensure fair competition and safety. The front brakes use larger discs (325-345mm) to handle more braking force, while the rear uses smaller discs (260-280mm). Teams must stay within these measurements or face penalties.

• Front brake discs must be between 325-345mm in diameter
• Rear brake discs must be between 260-280mm in diameter
• These limits ensure all teams use similar braking technology
• Disc sizes affect how quickly a car can decelerate before corners
