Brake fluid specifications
The medium in the hydraulic brake system is called brake fluid and is used to transfer pressure from e.g. a brake pedal via a master brake cylinder, which in turn actuates the brake calipers.
Recommended grade: Volvo Original or similar fluid that meets a combination of Dot 4, 5.1 and ISO 4925 class 6.
Note
Changing or filling brake fluid should be entrusted to an authorized Volvo workshop.
