X. 9940 To HS.{Lord Ernest Hives - Chair} from DA.{Bernard Day - Chassis Design} S E C R E T. DA{Bernard Day - Chassis Design}2/M22.5.24. E.A.C. BRAKE LINKAGE. X.9940. Referring to HS{Lord Ernest Hives - Chair}/ACL1/LG19.5.24., we agree that it is necessary to experiment to get the exact suitable ratio of braking between front and back, and we suggest that this should be gone into at first opportunity rather carefully, and a good proportion evolved before any alteration is made to the proport- ions of the balancing lever. It seems likely that there will be two dis- tributions of braking, one suitable for closed, and the other for open cars, but Mr. Royce now proposes to still further reduce the braking on the front to overcome the twisting of the axle, and consequently the figures we have given you will require still further modification.
