| To DA. {Bernard Day - Chassis Design} from Hs {Lord Ernest Hives - Chair} /Rm. {William Robotham - Chief Engineer} X8450 Hs {Lord Ernest Hives - Chair} /Rml/LG17.9.27. 10-EX - FRONT BRAKES. X8774 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 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 incorporate damper something on the lines of the revised rear brake drum for the Phantom.
