This SAE Standard documents dimensional metric specifications for hydraulic brake system threaded ports and banjo bolts for the interconnection of major components in automotive hydraulic brake systems. Banjo blocks are not covered by this document. The purpose of this document is to recommend preferred metrically dimensioned components (including alternative choices). Some applications may require sizes or forms other than those shown herein, and this document does not preclude such other details when they are required.
This document has been determined to contain basic and stable technology which is not dynamic in nature. Design Authorities should conside using the more recent metric tube connection designs in SAE J2879 for new designs. This determination should be made by each Design Authority.
