Abstract

This SAE Information Report is the listing of recommendations for shelf storage for hydraulic brake components. Included in brake components are wheel cylinders, master cylinders, combination valves, and disc brake caliper assemblies. This document is not a specification. This document embodies the analyses and experiences of many users and manufacturers. Where specific manufacturers' recommendations are made, those recommendations shall supersede the recommendations of this document. This document lists the successful procedures and practices associated with brake components based on long experience of a wide cross section of manufacturers and users. The practices are expected to be applied to all brake components where SAE standards are applicable. Background Hydraulic brake components in storage are not filled with brake fluid and are subject to environmental conditions from which they are protected after vehicle installation and when filled with fluid. All polymeric materials such as rubber and plastic parts undergo degradation in physical properties when stored over an extended period of time in an incompatible environment. Degradation can be evidenced by cracking, hardening and/or softening of the material. Metal parts are also subject to corrosion and physical damage due to adverse storage environment. Detrimental changes can be minimized by controlling this storage environment. Rationale Changes were made to better clarify potential circumstances to benefit the reader of this document. The changes are included in paragraph 1.1 relating to cracking, hardening and or softening; paragraph 3.3 to note potential low temperature performance changes; 3.7 including atmosphere as well as solution; adding 3.9.1 to illustrate potential effects of heating/air conditioning vents on components.
