  Brake System ğon Ingram MikeCiurylo

  FSAE Braking Rules Thecar must be equipped with a braking system that acts on all four wheels and is operated by a single control. It must have two independent hydraulic circuits such that in the case of a leak or failure at any point in the system, effective braking power is maintained on at least two wheels. Each hydraulic circuit must have its own fluid reserve, either by the use of separate reservoirs or by the use of a dammed, OEMstyle reservoir. The brake system must be capable of locking all four (4) wheels during braking test. › “Brake—by—wire” systems are prohibited.
