Federal Motor Vehicle Safety Standards-Motor Vehicle Brake Fluids

概要

This document proposes technical modifications in two of the tests included in our standard on brake fluid, i.e., the evaporation test and the corrosion test. The purpose of the modifications would be to improve the repeatability and reproducibility of the tests. This document also requests comments concerning retention of the evaporation test. A committee of the Society of Automotive Engineers, which originally developed the test, recently voted to delete the test from its standard on brake fluid. While we have tentatively concluded that the test should remain in our standard, we are requesting comments on that issue.
