| To DA.{Bernard Day - Chassis Design} from Hs{Lord Ernest Hives - Chair}/Rn.{Mr Robinson} X8774 Hs{Lord Ernest Hives - Chair}/Rml/LG17.9.27. 10-EX - FRONT BRAKES. X8774 X8420 [struck through] On the sports car we intend to increase the front braking. At the present moment the very flexible drums allow a lot of lost movement on the brake levers. Increasing the front braking will increase the rate of wear and also exaggerate the lost movement through the brake drums [handwritten: distortion]. Flexible drums were only introduced to stop brake jaggers which cannot now exist owing to the torque control on the axle. We should like a scheme for the front brake drums of the Phantom which would make them rather more rigid and [struck through: incorporate damper] something on the lines of the revised rear brake drum for the Phantom.
