| 73409 To By.{R.W. Bailey - Chief Engineer} from Hs{Lord Ernest Hives - Chair}/Rm.{William Robotham - Chief Engineer} Hs{Lord Ernest Hives - Chair}/Rm.{William Robotham - Chief Engineer}14/KW.13.12.34. Duron Brake Linings. With reference to the attached, some Duron brake linings have already been submitted to us by Mr. E.R. Hall. Our current practice is to test all linings on the servo before fitting to the car, as this enables us to determine their general characteristics with a minimum of expense. We tested the Duron linings and as you will see they are affected by temperature more than some Ferodo linings. Unless therefore Mr. Bailey has some new material, we do not see the object of discussing the matter with him at the moment. Hs{Lord Ernest Hives - Chair}/Rm{William Robotham - Chief Engineer}: | ||
