The FIA has scrapped its plans for 2021 to impose on F1 teams a standard brake system that included common disks and friction components for all cars.
The sport's governing body says it wants to assess the performance of F1 cars under the future rules before it eventually introduces a standard supplier brake system.
"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," said the FIA in a statement released on Friday.
"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."
Italian manufacturer Brembo had won the initial tender for the brake system
"The FIA would like to thank the preselected bidder, Brembo, for providing a thorough and sound proposal based on the specifications supplied to it," added the FIA.
"Nonetheless, and in light of the considerations regarding car performance mentioned above, it has been decided to reassess the situation in 2021."
