Brake fluid — general information (Vesta 2180)

Brake fluid is used in the hydraulic brake drive and in the hydraulic clutch release drive. In the braking system, fluid transmits force from the master brake cylinder to the working (wheel) cylinders.

The brake fluid consists of a base consisting of polyglycols and their esters or silicones, and additives. Additives must protect metal parts of the brake system from corrosion.

Brake fluids are manufactured according to J1703, ISO (DIN) 4925 and FMVSS 116 standards. The brake fluid class for a specific vehicle is determined by its manufacturer.

The manufacturer is obliged to indicate the base of the brake fluid on the packaging. Domestic and imported fluids of classes DOT 3, DOT 4 and DOT 5.1 can be mixed in any proportions. The liquids have shades from light yellow to light brown.

Warning: DOT 5 brake fluids are silicone based and are not compatible with polyglycol fluids. Silicone-based liquids are dark red in color.
