| To By. {R.W. Bailey - Chief Engineer} from Rm {William Robotham - Chief Engineer} /AFM. {Anthony F. Martindale} C. DR. C. HPS. {Horace Percy Smith - Experimental Factory Mgr} 606 Rm {William Robotham - Chief Engineer} /AFM. {Anthony F. Martindale} 5/AP.20.10.37. WRAITH BRAKES The amount of front braking on Wraith has been increased in two ways both together. One was by a change of servo cams and the other by a new plate lever on the front equalizer, shown on N.Sch.3145. The result is that there is now too much front braking, the front wheels lock first on greasy roads. The front brakes wear out too quickly, being smaller than the rear brakes. We think the original plate lever GW.926 should be replaced on the front equalizer LOP, and if possible the six cars works are building should have it.
