Dear Mr. Theissen: This is in response to your letter of February 5, 1976, to Mrs Winifred Desmond of this agency concerning braking and rollover characteristics of the Jeep vehicle. We are sorry for the delay in our answer.; The Jeep Corporation is correct in saying that 49 CFR 571.105-75 *Hydraulic Brake Systems*, applies only to passenger cars. It will also apply to school buses manufactured after October 25, 1976. Part 575, Consumer Information Regulations, applies as a whole to all motor vehicles (49 CFR 575.4), but the consumer information item requiring reports on brake performance is limited to passenger cars and motorcycles (49 CFR S 571.101).; With regard to rollover resistance, the agency has issued an advanc notice of proposed rulemaking to collect information on rollover resistance, but no requirement to report on rollover performance exists at this time.; Yours truly, Stephen P. Wood, Assistant Chief Counsel
