Rm{William Robotham - Chief Engineer} PHANTOM 111. FRONT BRAKE CABLE. To deal with the trouble of the cable to the front brake being frayed through, either by trapping under the oil pump nuts or scraping along the front pan, as referred to in Rm{William Robotham - Chief Engineer}/CWH.5/N.15.8.38, Ha/SB.{Mr Bull/Mr Bannister}10/HR.26.8.38 and Hd{Mr Hayward/Mr Huddy}/B.1/HR.29.8.38., we have schemed a guide, shewn on G.CD.882 herewith. We think that if a cable is used, it will be necessary to have something of this sort, but an alternative is to use a rod instead of a cable, in which case a guide is not required. With the rod, we should like to introduce a shock damper in place of the present idler lever and air dash pot, as done on Bentley 111, at the same time reducing the length of the rod and avoiding the necessity of a steady. As this will require testing, we suggest that G.CD.882 should be detailed to deal with the actual trouble, and we shall take an early opportunity for producing a scheme of rod and damper in the hope of getting it in as soon as possible.
