| To Hs.{Lord Ernest Hives - Chair} from R.{Sir Henry Royce} c. to BJ. BY.{R.W. Bailey - Chief Engineer} X719 X5009 R17/110.6.26. RE. BRAKE MATERIAL. X.3409 X.4111 X.8420 (1) With regard to the new ferodo material E.{Mr Elliott - Chief Engineer} wonders whether it will alter its characteristics after becoming heated on a long downhill grade. (2) We are all naturally interested to know whether it is equally affected by moisture, such as washing the car. (3) The third is if there is variation after a car has been standing & due to the steel of the brake drums becoming rusty. It might be worth while to try stainless or staybright brake drums.
