Brake fluid – specifications

The medium in a hydraulic brake system is called brake fluid, and it is used to transfer pressure from e.g. a brake pedal via a master brake cylinder to one or more slave cylinders, which in turn act on a mechanical brake.

Prescribed grade: Brake fluid that fulfils a combination of Dot 4, 5.1 and ISO 4925 class 6.

 Note

It is recommended that brake fluid is changed or filled by an authorised Polestar workshop.
