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: Volvo Original or equivalent fluid compliant with a combination of Dot 4, 5.1 and ISO 4925 class 6.
It is recommended that brake fluid is changed or filled by an authorised Volvo workshop.
