Dear Mr. Martin: This responds to General Motors Corporation's May 27, 1976, petition t commence rulemaking to amend Standard No. 105-75, *Hydraulic Brake Systems*, in order to return one sentence to the text of S5.1.5.2(a) that was omitted in a September 17, 1975, revision of that section (40 FR 42872). The sentence reads:'However, the maximum control force for the fifth stop in the case of a vehicle manufactured before September 1, 1976, shall be not more than plus 60 pounds of the average control force for the baseline check (but in no case more than 110 pounds).'; The National Highway Traffic Safety Administration considers a petitio to amend the standard to be unnecessary because the omission was inadvertent and did not constitute a substantive change to the requirements of the standard. Therefore, an interpretative amendment to conform the language to that intended will be forthcoming in the near future. Interested persons are notified that the interim control force value has been in effect for all vehicles of 10, 000 pounds gross vehicle weight rating or less despite the omission of the sentence on September 17, 1975.; Thank you for bringing this omission to the attention of the agency. Yours truly, Frank Berndt, Acting Chief Counsel
