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.
