Requesting experiments to find variations in braking due to surface conditions and compare wear rates.

| To Hs.{Lord Ernest Hives - Chair} from R.{Sir Henry Royce} X9940 R2/M11.12.23. FOUR WHEEL BRAKES. X.1559 - Y4388 [Struck through] X. 9940 Will you please make definite experiments to find out the variations in braking due to the condition of the surfaces? I still fear that there is brake variation due to the condition of the surfaces, independent of bedding. With reference to Halo is this more consistent, and what is the rate of wear as compared with Ferodo? R.{Sir Henry Royce} | ||
