To Rm{William Robotham - Chief Engineer}/IMW.{Ivan M. Waller - Head of Chateauroux} from Rm{William Robotham - Chief Engineer}/AFM.{Anthony F. Martindale} Chateauroux. 600a Rm{William Robotham - Chief Engineer}/AFM.{Anthony F. Martindale}6/MH.{M. Huckerby}5.2.38. 26.G.VI BRAKES. Reference your memo to Rm.{William Robotham - Chief Engineer} 2/2.2.38.. You say there is 3 1/2" useful pedal movement. You must allow 1" movement approx. for servo wear and something more for clearance under pedal. The figures you send us sound most reasonable, a standard Bentley pedal goes to the board if the rear brakes are 3 notches out of adjustment. The car came out of the shop after the most recent brake alterations and little time was allotted to brake setting, the brakes appearing to work reasonably. We did remove a "click" on brake application by shortening an equalizer rod. It is possible that the rods to the rear of the bell cranks need shortening, and the rods from servo to rear equalizer lengthening, to get maximum advantage from brake set up. You are doubtless quite familiar with the procedure for setting a combined hand and foot brake system, if you wish to alter anything, but we do not agree that any stops need modification.
