| To Hs.{Lord Ernest Hives - Chair} from DA.{Bernard Day - Chassis Design} contd :- DA{Bernard Day - Chassis Design}1/M9.6.25. We have looked into the question of altering the proportion of direct braking, and find that quite a considerable alteration does not make much difference to the distribution of braking for servo efficiencies within the range we are likely to get.
