Borate Ester Based Brake Fluids
- Ground Vehicle Standard
An error has been found in the J1704 10/2000
published standard. The following disclaimer explains the
correction to the error:
As Balloted by the "Motor Vehicle Brake Fluids Committee" the October 2000 revision of SAE J1704 was intended to remove all references to zinc strips and associated zinc strip testing. However, the reference to zinc test in the test procedure 5.6 Corrosion was overlooked. This reference to zinc test strips will be removed in the next update.
This SAE Recommended Practice was prepared to provide engineers, designers, and manufacturers of motor vehicles with a set of minimum performance standards which covers the next level of performance properties above those of the present SAE J1703 brake fluid standard. These fluids are not intended for use under arctic conditions or in braking systems requiring the use of mineral oil based hydraulic fluid. 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 terpolymer of ethylene, propylene, and a diene (EPDM). These fluids are not designed to operate in a pumped or a clutch braking system, especially those hydraulic systems requiring a mineral oil based fluid.
Data Sets - Support Documents
The scope of the Brake Fluids Standards Committee is to develop and maintain relevant standards; recommended practices and information reports related to non-petroleum based brake fluids covering: The requirements of fluids for use in the hydraulic brake systems of motor vehicles; the handling, dispensing, and packaging of such fluids; service maintenance using such fluids. These documents are reviewed on a regular basis to ensure that they reflect the changing needs and requirements of the industry.
