From Hs{Lord Ernest Hives - Chair}/Rm.{William Robotham - Chief Engineer} c. to Da.{Bernard Day - Chassis Design} x7420 Hs{Lord Ernest Hives - Chair}/Rm.{William Robotham - Chief Engineer}4/J.6.2.30. x7570 x7360 x7470 PHANTOM II REAR FOOT BRAKE. In spite of the reduced direct braking leverage, we are finding that the total travel on the Phantom II 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 all Ferobestos on the front brakes in order to avoid squeaks. HS{Lord Ernest Hives - Chair}/Rm.{William Robotham - Chief Engineer} | ||
