Cont'd.{John DeLooze - Company Secretary} The steering box is still leaking oil slightly from the centre joint faces at either side. Riding. The front of the car has rode heavy throughout the mileage. It was at first attributed to the roll rod, but upon disconnecting the roll rod, no improvement was made. It was evident that either the loads of the front dampers were unusually high, or partial seizure of the dampers had taken place. The rear seats gave a good ride under all conditions. Brakes. Under normal conditions the braking was good. We found, however, that when driving all out on a down gradient, then applying the brakes fairly hard (i.e. not attempting any stunt) the brakes were very effective then died off and no more load could be applied to the pedal. Upon investigating the cause, it was found that the servo had come on to the stop. This should not have occurred, as the brake clearances were not in a condition to be taken up. With the fitting of the new type swinging arm to the servo, we suspect differences in leverages may have arisen. Clutch. The clutch became no worse for the slight jagger and final grab during the run. When changing under load on the hills, the drive was taken up very smoothly. In traffic there was no sign of slipping and a considerable amount of this work was carried out. Electrical system. The latest three point suspension to scheme D.54742 for the electric horns has failed. On the NS{Norman Scott} horn, one of the legs broke near the centre flange during the first days run. The Off-side three legs broke away from the centre flange during the third days run. Both horns failed to operate during the second days run. The enamel under the suspension bracket and on the bracket of the pillar had not be cleaned off leaving no positive earth connection. | ||
