My Proposal – Technical Regulations – Chapter 11

ARTICLE 11: BRAKE SYSTEM

1. Brake circuits and pressure distribution
   1. With the exception of a power unit, all cars must be equipped with only one brake system. This system must comprise solely of two separate hydraulic circuits operated by one pedal, one circuit operating on the two front wheels and the other on the two rear wheels. This system must be designed so that if a failure occurs in one circuit the pedal will still operate the brakes in the other.
   2. The brake system must be designed so that within each circuit, the forces applied to the brake pads are the same magnitude and act as opposing pairs on a given brake disc.
   3. Devices which are capable of altering the configuration or affecting the performance of any part of the brake system are allowed.
   4. Any change to, or modulation of, the brake system, whilst the car is on the track must be made by the driver’s direct physical input or by the system.
      
2. Brake calipers
   1. Brake calipers are defined as the parts of the braking system outside the survival cell, other than brake discs, brake pads, caliper pistons, which are stressed when subjected to the braking pressure. Bolts or studs which are used for attachment are not considered to be part of the brake calipers.
   2. No restrictions on the brake calipers materials as long as with a modulus of elasticity no greater than 80Gpa.
   3. No restrictions on their number and design.
      
3. Brake discs and pads
   1. No restrictions on the number of brake discs allowed on each wheel
   2. Design and technology of manufacturing are not restricted as long as compliant with the safety and impact tests.
   3. Brake pads are permitted on each wheel. Cooling holes are also permitted in the pads.
      
4. Brake pressure modulation
   1. No braking system may be designed to increase the pressure in the brake calipers above that achieved by the driver applied force to the pedal under all conditions.
   2. Braking system may be designed to prevent wheels from locking when the driver applies pressure to the brake pedal.
      
5. Liquid cooling
   Braking cooling is allowed, in any form, including liquid, as long as the liquid used is not dangerous for the environment or for people operating with the car in any circumstances when the liquid is exposed (i.e. after a crash).
   
6. Rear brake control system
   The pressure in the rear braking circuit may be provided by a powered control system.
   
7. Supply of Brake Friction and Brake System Hydraulic components
   Competitors have complete freedom in the choice of supplier(s) for any component of the braking system as long as they can provide a system fully compliant with the above rules.
