Bailey - Chief Engineer} From Hs{Lord Ernest Hives - Chair}/Rn.{Mr Robinson} c. to Da.{Bernard Day - Chassis Design} Hs{Lord Ernest Hives - Chair}/Rn.{Mr Robinson}4/MJ.6.2.30. PHANTOM 11 REAR FOOT BRAKE. X.7370 X.7360 E.7420 X.3409 In spite of the reduced direct braking leverage, we are finding that the total travel on the Phantom 11 increases too rapidly when Ferobestos is used. We therefore recommend that Ferodo Bonded Asbestos should be fitted to the rear foot brake shoes until we have the increased area of brake lining which we are running on our next 10,000 miles test car. We suggest that the existing stock of Ferobestos could be used for the hand brake liners to avoid scrap. We are, of course, bound to continue to use Ferobestos on the front brakes in order to avoid squeaks. Hs{Lord Ernest Hives - Chair}/Rn.{Mr Robinson} | ||
