MILEAGE 1433 1488 1779 2931 2981 4534 4788 5125 7757 8888 9844 10352 CAUSE AND REMEDY New type springs fitted " " " Car driven at high speed over Cassis. " Faulty brazing. " Carriers too weak - condemned. " Probably due to carrying large spare tin of petrol and battery on running board. " TOTAL MILEAGE 10,352 at average speed - 39.6 m.p.h. All brake parts examined after test. Very little wear taken place. Excessive wear on front brake actuating shafts and front brake equaliser, otherwise in very good condition. Slight wear in steering nut, but not excessive. Silichrome steel valves were used in this engine and run with no tappet clearance. They were not touched during the test and were in excellent condition afterwards. No jaggers occurred after brake drums were turned down. Very little wear on Front brake shoes. Brakes required re-lining after test. Servo adjustment during test - nil. Dynamo on engine gave no trouble and is a vast improvement. EXPERIMENTAL REPORT.
