Dear Mr. Kamath: This responds to your October 8, 1974, question whether a front axl automatic pressure limiting valve may be removed during the burnish procedure to permit effective burnish of the front brakes.; The answer to your question appears in Notice 6 to Docket 74-10 i response to a similar inquiry from International Harvester. A copy of that notice is enclosed for your information. It amends S6.1.8.1 to require that any automatic pressure limiting valve be in use except in the case where the temperature of the hottest brake on a rear axle exceeds the temperature of the hottest brake on a front axle by more than 125 degrees F. A bypassed valve is reconnected if the temperature of the hottest brake on a front axle exceeds the temperature of the hottest brake on a rear axle by 100 degrees F.; Yours truly, Richard B. Dyson, Acting Chief Counsel
