Brake fluid shall be deemed to be adulterated unless it meets the minimum standards for purity and quality as such standards for brake fluid are established by the State Board of Agriculture and Industries under the provisions of this article. Brake fluid shall also be deemed to be adulterated if it contains any substance or preparation which renders it unsuitable for use as a brake fluid or will impair the normal operation of a hydraulic brake system.
