Lee Evans - Chassis Test Manager} [Text is struck through] E.2/HP.15.9.36. Phantom III Brakes. ------------------ Replying to your memo Hs{Lord Ernest Hives - Chair}/Gry.{Shadwell Grylls}5/KW.14.9.36, we have looked into this matter, and we agree that there is a foul between the end of the pinch bolt nut on the brake lever and one of the cap nuts on the hambone, but it does not limit the travel to the extent that you state. Our investigation shows that the bottom 14% of the movement of the lever is lost. We believe this part did originally clear, but as the length of the lever has been modified once or perhaps twice it has resulted in this loss of travel, about 1/7th. The arrangement drawing G.83342 actually shows the brake lever horizontal instead of in its initial position, .825" above the horizontal. Personally I think this is not sufficiently serious to justify going round and changing all cars. We are issuing a modification N.Sch.4904 showing the bosses on the end of the split brake lever shortened, and a lock nut fitted and riveted up in place of the present nut and split pin. Hs{Lord Ernest Hives - Chair}/AFM{Anthony F. Martindale} is having a lever made to these particulars at the moment, so that as soon as we are satisfied the modified instructions can be issued for production. We should be glad if BY.{R.W. Bailey - Chief Engineer} will have the brake lever on G.83342 shown in its initial position. E.{Mr Elliott - Chief Engineer} [Signature] | ||
