Dear Mr. Joyce:#This responds to your June 18, 1975, question whethe S5.3 of Standard No. 105-75, *Hydraulic Brake Systems*, requires that the brake fluid level warning system specified by S5.3.1 be instantaneous when the brake fluid level reaches the condition described in S5.3.1(b).#The answer to your question if no. The National Highway Traffic Safety Administration recognizes that a minimal interval between the occurrence of the specified condition and the appearance of the required signal is a physical fact. I enclose a copy of an interpretation of a similar require- ment of Standard No. 105-75 for your information. In the case of the brake fluid level indicator, a time interval that is insignificant with respect to the time required to respond to the signal would be permissible.#Sincerely,Frank A. Berndt,Acting Chief Counsel;
