This document applies to 90 degree double inverted flares used on common sizes of automotive hydraulic brake tubes, and their associated tube nuts and mating ports. The intent of this standard is to replace the use of SAE J512 and SAE J533 for automotive hydraulic brake tube connections.

This SAE Standard covers performance requirements and methods of test for master cylinder reservoir diaphragm gaskets that will provide a functional seal and protection from outside dirt and water.

This recommended practice provides a method, test set-up, and test conditions for brake hydraulic component flow rate measurement for high differential pressure (>5 bar) flow conditions. It is intended for hydraulic brake components which affect the brake fluid flow characteristics in a hydraulic brake circuit, that are part of a circuit for which the flow characteristics are important to system operation, and that are exposed to high operating pressure differentials (in the 5 to 100 bar range). Typical applications may include measurement of flow through chassis controls valve bodies, orifices in the brake system such as in flow bolts, junction blocks, and master cylinders, and through brake pipe configurations.

This SAE Recommended Practice specifies the performance test procedures and requirements of a plastic reservoir assembly suitable for use on a hydraulic brake master cylinder (reference SAE J1153). Intended usage is for on-road vehicles using brake fluid conforming to fMVSS-116 (DOT 3), and SAE J1703 specifications. This document includes the cap.cover and diaphragm as integral parts of the reservoir assembly. The fluid level sensor (FLS) is also included as an integral part of the assembly. However, additional FLS standards and/or requirements are applicable and necessary which are not covered in this document. This document is intended to provide a recommended practice and minimum performance requirements of current established designs on those reservoir assemblies generally used by individual manufacturers which have demonstrated satisfactory field performance. This document is applicable to new reservoir assemblies for commercial or aftermarket production.

This SAE Standard covers performance requirements and methods of test for master cylinder reservoir diaphragm gaskets that will provide a functional seal and protection from outside dirt and water.

The scope of this new recommended practice should include, but not necessarily be limited to: 1. Define vehicle operating conditions used to drive MOC-EPB actuator design and selection 2. Define brake corner operating conditions (e.g. temperature and state of burnish) used to drive MOC-EPB actuator design and selection 3. Define actuator operating conditions (e.g. temperature, voltage, current limit, and state of wear) used to drive MOC-EPB actuator design and selection 4. Define methodology for addressing part to part variation in performance

This SAE Recommended Practice applies to valve assemblies that are used on passenger car and light truck braking systems utilizing motor vehicle hydraulic brake fluids. The procedure (SAE J1118) and these requirements (SAE J1137) were developed for brake fluids conforming to SAE J1703 and FMVSS 116 (DOT 3) requirements; however, it may be utilized for valves which use DOT 4 or DOT 5 brake fluid. These requirements are applicable to differential warning, metering hold off, bypass function, or proportioning type valves or any combination thereof.

The Recommended Practice specifies minimum performance and durability requirements for satisfactory vehicle usage, and it is applicable to new valve assemblies from commerical production and re-manufacture (factory rebuild).
