The FIA has recommended all Formula E teams review their braking systems after an accident during the Diriyah E-Prix left Edoardo Mortara hospitalized.
Ahead of rounds 3 and 4 at Rome, the FIA has asked all teams to review their Failure Mode and Effects Analysis (FMEA) of their braking systems. Manufacturers must then submit a list considering all scenarios relating to an issue in order to clear their cars.
“Especially if the driver loses the front brake for any reason (leakage, calliper issue), the system must be able to detect that and activate the reak braking (regen or BBW actuation),” reads a release from technical delegate Laurent Arnaud.
“In the chassis supplier common package, [teams] have the displacement travel sensor from the tandem brake master cylinder. Those sensors must be used to detect any leakage on the brake system,” the statement continued.
This relates to Mostara’s crash, in which the front brakes recorded zero pressure, likely the result of a leak. However, the FIA clarified the cause of the incident is not fully identified, but that there is “no concern on the chassis common parts.”
