Brake fluid specifications
The medium in the hydraulic brake system is called brake fluid and is used to transfer braking force from e.g. pressure on the brake pedal via a master brake cylinder to one or more slave cylinders, which in turn act on a mechanical brake.
Recommended grade: Volvo Original Dot 4 class 6 or equivalent.
Note
Changing or filling brake fluid should be entrusted to an authorized Volvo workshop.
