| To Hs. {Lord Ernest Hives - Chair} & BY. {R.W. Bailey - Chief Engineer} from DA. {Bernard Day - Chassis Design} c. to BJ. Wer. Hm. {Capt. W. Hallam - Head Repairs} (5370. dal/M25.4.27. BRAKES. X.5420 X.5370 R. {Sir Henry Royce} has heard of a 20 HP. car which was complained of because of a knock on application of the brakes. It was stated that this trouble was dealt with by easing off the brakes, and so completely spoiling them. R. {Sir Henry Royce} thinks that this should never be done, but that the flexibility in the servo operation, which has recently been provided and standardised, should be fitted to all cars - 20 HP. and Phantom.
