This SAE Recommended Practice covers the application of hydraulic brake hose (as defined by current issue of SAE J1401) as used to provide a flexible hydraulic connection between wheel end or axle brake system components on motor vehicles. The purpose of this document is to outline design, operating, and service factors in routing a hydraulic brake hose assembly to a vehicle. It is intended to serve as a recommended practice for original equipment manufacturers. Vehicle design circumstances may exist that prevent strict adherence to this document. Any deviations should have the concurrence of all engineering functions involved.

This specification covers hose fabricated from wire braid and synthetic rubber, assembled with end fittings for use in automotive applications up to 10.3 MPa (1500 psi) maximum pressure, as flexible connections within the temperature range of -40 °C to 121 °C (-40 °F to +250 °F) average, 13.5 °C (275 °F) maximum peaks. The specification in this SAE Standard originated in the SAE-ASTM Technical Committee on Automotive Rubber (other than tires). They represent the correlation of the best information available from research investigation and production experience on the minimum constructional and performance characteristics essential for new power steering assemblies used as original or replacement equipment. This standard applies to passenger cars. It may prove useful to truck manufacturers, but it is not to be presented as present practices.
