Please receive herewith the following scheme :- P.CD.486 Brake Pedal Lever with Ph.111 Quadrant. The above scheme shows the brake quadrant moved inwards .450 to increase the clearance between the pull rod and the change gear cover. We have used the Ph.111 double quadrant for this purpose instead of the single one at present fitted, and also moved the lever on the intermediate shaft inwards in line.
