| TO HS.{Lord Ernest Hives - Chair} FROM R.{Sir Henry Royce} ORIGINAL R2/M11.12.23. FOUR WHEEL BRAKES. V1555 / X9940 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} | ||
