This SAE Recommended Practice defines minimum requirements for general characteristics, performance, and durability. 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 general characteristics and test procedure are specified in SAE J1693.
This document has been determined to contain basic and stable technology, however it does not specifically represent the current state of the art design of tandem master cylinders for passenger vehicles and light trucks. Although this Recommended Practice is not directly applicable to many current master cylinder designs, it does incorporate procedures and requirements that can be appropriate and beneficial. Many aspects of these can be applied to designs of the same or similar concept including aluminum body as well as more current state of the art designs.
