| To HS.{Lord Ernest Hives - Chair} from Da.{Bernard Day - Chassis Design} SECRET 2. DA{Bernard Day - Chassis Design}2/HS.{Lord Ernest Hives - Chair}4.25. Handwritten: X4257 GOSHAWK. X.4259 X.4257 SQUEAKING BRAKES. A further suggestion which I meant to have sent you yesterday was that the squeaks may be due to the high pressure per square inch on the foot brake, which as you know is about twice as high as the 40/50. If there is anything in this, the new India chassis with brakes nearly twice as wide as the existing Goshawk should shew signs of improvement. DA.{Bernard Day - Chassis Design} | ||
