Dear Mr. Walker: This responds to your November 18, 1974, request for copies of an Federal braking standards for horse trailers.; The National Highway Traffic Safety Administration has responsibilit for the issuance of Federal motor vehicle safety standards, and we have issued only one standard in this area. The standard applies to trailers that are equipped with air brakes (Standard No. 121, *Air brake systems*, 49 CFR 571.121). This standard becomes effective for trailers which are manufactured after January 1, 1975.; Therefore there are no Federal brake standards which apply to the hors trailer you describe.; Yours truly, Richard B. Dyson, Acting Chief Counsel
