本SAE推荐规程规定了一般特性和试验程序，以定义最低特性、性能和耐久性要求。它仅适用于再制造组件（工厂重建）。本文件适用于现有设计的主缸总成和部件，但不包括液位传感器、整体比例阀或防抱死制动或牵引力控制系统中使用的主缸。这些将由其他标准涵盖。SAE J1694规定了最低特性、性能和耐久性要求。

This SAE Recommended Practice specifies the general characteristics and test procedure to define the minimum characteristics, performance, and durability requirements. It is applicable to remanufactured assemblies (factory rebuild) only.This document applies to master cylinder assemblies and components of current established designs but does not cover fluid level sensors, integral proportioning valves or those master cylinders used in anti-lock brake or traction control systems. These will be covered by other standards.The minimum characteristics, performance, and durability requirements are specified in SAE J1694.
