Brake Fluid
Brake Fluid A brake fluid meets the international standards set in the United States by the Society of Automotive Engineers (SAE) and Department of Transportation Federal Motor Vehicle Safety Standard (FMVSS). The major characteristics of a brake fluid include : (a) Low viscosity. The brake fluid must flow easily over a wide temperature range and be able to operate in very cold conditions. (b) Compatibility with rubber components. Besides resisting corrosion of metal parts, it must be chemically non-reactive to the rubber seals etc. It must be non-injurious to the system. (c) Lubricating properties. It must reduce friction of moving parts, especially rubber seals. (d) Resistance to chemical ageing. It should have a long storage life and be stable when in use. (e) Compatibility with fluids. It must be compatible with other fluids of its type. if) High boiling point. Most braking systems use a glycerin-alcohol (glycol) fluid with additives to meet the required specifications. Because of
