The FIA has confirmed that it will delay a switch to standardised brake components, which it had hoped to implement for the 2021 Formula 1 season.
As part of the FIA's cost saving measures, it has looked at introducing a number of standardised parts which would see just one company supplying the entire grid.
Brakes were included on this list and Italian supplier Brembo had been preselected as the preferred bidder, but the FIA says this move will now be delayed for "safety and performance" reasons, as the "real-world performance" of the 2021 cars isn't yet known.
In a statement, the FIA said: "To allow further evaluation of the real-world performance of 2021 Formula 1 cars, the FIA has chosen to delay the potential implementation of single suppliers for brake friction materials and brake system components.
"The significant regulation changes and their interpretation by the teams will affect multiple aspects of the 2021 cars, and considering the critical role of the brakes in both safety and performance, the FIA has decided to cancel both the selection process for brake systems and for brake friction materials in F1 until further studies can be undertaken.
"The FIA would like to thank the preselected bidder, Brembo, for providing a thorough and sound proposal based on the specifications supplied to it.
"Nonetheless, and in light of the considerations regarding car performance mentioned above, it has been decided to reassess the situation in 2021."
