SAE J1703 pdf download.Motor Vehicle Brake Fluid.
This SAE Standard covers motor vehicle brake fluids of the noripetroleum type for use m the braking system of any motor vehicle such as a passenger car, truck, bus, or trailer. These fluids are not intended br use under arctic conditions. These fluids are designed for use in braking systems fitted with rubber cups and seals made from natural rubber (NR). styrene-butadiene rubber (SBR), or a terpolyiner of ethylene, propylene. and a diene (EPDM).
