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.
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.
Figure 3 represents the typical cast iron master cylinder for which this standard was developed. Equivalent designs, regardless of materials utilized, could employ portions of this Recommended Practice to evaluate remanufactured products.
