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.
