| 606 To By. {R.W. Bailey - Chief Engineer} c. to Da. {Bernard Day - Chassis Design} Rm {William Robotham - Chief Engineer} /JBD. {John B. Dixon - Fuel Systems} &/JH.17.3.39. WRAITH BRAKES. We have experienced a foul on the Wraith brakes. This occurs when the pin is inserted the wrong way round in the top of the equalizing lever between the front and rear brakes on the servo, causing a foul in the aluminium drop arm. Admittedly this is caused only when the pin is inserted the wrong way but as this is easily done and there does not seem any reason why the aluminium arm should not be reduced in section to clear the pin which ever way it is inserted, we consider this should be modified to make it fool proof.
