Brake Servo. Now that the major clonk from the servo is stopped by the special rubber stop on the reverse link, another click is audible on release. This is caused by the servo cam lever coming back against the stop which acts instead of a pedal stop. A rubber stop here, in addition to those called for on the rear bell crank stops, will be required for freedom from noise on release. ------------------- Rm{William Robotham - Chief Engineer}/IMW.{Ivan M.
