J1401_201302 Road Vehicle - Hydraulic Brake Hose Assemblies for Use With Nonpetroleum-Base Hydraulic Fluids

This revision contains three main updates. The first update is to the internal diameter categories. A gap exists in between the categories, and this gap could result in ambiguity of requirements for new brake hoses with new internal diameters. This revision has been recommended for adoption into FMVSS 106. The second update is to the brake fluid specification. This specification now refers to both DOT 3 and DOT4 fluids. Also, the composition of the Compatibility Fluids is changing more rapidly. It makes more sense to place a reference to SAE J1703 and SAE J1704 instead of updating many specifications each time the Compatibility Fluid is changed.

The third update is the requirement for identification yarn. The Automotive Brake and Steering Hose Committee has determined that the identification yarn is not necessary. Brake hose identification information can be found on fitting stamps and the printing on the outside diameter of the hose material. The identification yarn requirement has been declared optional.
