SAE J2053

Description / Abstract: This SAE Standard specifies the performance test procedures and requirements of a plastic reservoir assembly suitable for use on a Hydraulic Brake Master Cylinder (reference SAE J1153). Intended usage is for on-road vehicles using brake fluid conforming to FMVSS 116 (DOT 3), SAE J1703, and SAE J1704 specifications. This document includes the cap/cover and diaphragm as integral parts of the reservoir assembly. The fluid level sensor (FLS) is also included as an integral part of the assembly. However, additional FLS standards and/or requirements are applicable and necessary which are not covered in this document.

Purpose

This document is intended to provide minimum performance requirements of current established designs on those reservoir assemblies generally used by individual manufacturers which have demonstrated satisfactory field performance. This document is applicable to new reservoir assemblies for commercial or aftermarket production.
