| contd:- The wear of the brakes is the same: the heat and wear of the servo is less because of the greater angle of action. This I know we were going to increase over the Hispano, but we can still further incrase it until 80° is not unmanageable for angles according to my setting out. The equaliser for the back brakes can be thus, or small carrier shaft can be used - SEE ORIGINAL FOR SKETCH. R.{Sir Henry Royce} | ||
