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 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.

The SAE Recommended Practice specifies a standardize method and test procedure to measure low pressure differential (< 1bar) brake component brake fluid flow performance. The standard can be utilized for flow measurements across hydraulic brake components such as master cylinders, apply system to chassis controls piping, or other sources of flow restriction in the low pressure side of the hydraulic brake system. It covers materials, manufacturing processes, and general properties required to meet the wide range of service encountered in automotive application. This specification covers only low pressure differential fluid flow and does not include measurement recommended practice for High Pressure differential (> 1 bar) flows.

The SAE Recommended Practice specifies the test procedure to assure valve assemblies which are satisfactory for vehicle usage, and it is applicable to new valve assemblies for commercial production. It covers such valves where they are employed in passenger car and light truck brake systems utilizing motor vehicle hydraulic brake fluids. This procedure and requirements (SAE J1137) was developed for brake fluids conforming to SAE J1703 and FMVSS 116 (DOT 3); however, it may be utilized for valves which use DOT 4 or DOT 5 brake fluid. These procedure specifications were developed for base brake operation and do not consider the effects of ABS (anti-lock brake systems) or traction control systems which may have a significant effect on the valve. Careful analysis of the particular type ABS and/or traction control (if included in the system) should be made and additional tests are required which are not included in this document.
