Sidgreaves - MD} WOR.{Arthur Wormald - General Works Manager} BY.{R.W. Bailey - Chief Engineer} BENTSPORT BRAKING SYSTEM. R.{Sir Henry Royce} wishes it to be accepted as a principle that when we go in for hydraulic operation of the brakes we should dispense with the mechanical servo. This will be possible because it is easy to arrange an effective automatic adjustment on an hydraulic system, and the use of this automatic adjustment on an hydraulic system, will enable us to employ the full stroke of the pedal from the beginning and so obtain our braking by increased leverage. With reference to the mechanical system we are proposing shortly to go over this with a view to eliminating all the friction possible, and to devise, if we can, an improved balancing gear to replace the present bevel differentials which in some respects do not seem to be ideal.
