Product Code:SAE J1406
Title:Application of Hydraulic Brake Hose to Motor Vehicles
Issuing Committee:Automotive Brake And Steering Hose Standards Comm
Scope: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 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.
