| - 7 - under the scuttle will not stay on. We have had no trouble during the continuation of the test with the lamps not staying in their upright position. "Houdaille" front shock absorbers & connecting links. The shock absorbers have functioned quite satisfactorily. A slight oil leak has developed through the bearings during the continuation of the run. The quantity is small, as it has not been necessary to add further oil to the shock absorbers. No further adjustment has been necessary to the connecting links. Standard rear axle. This is still in good condition. It has remained oil tight, & is still good as regards noise. Rear brakes & actuating shafts. Re metal dirt excluders on rear actuating shafts to G.L.152. Re metal dirt excluders, we find that besides these becoming damaged through stones hitting same, they have somewhat collapsed towards the centre, due to the metal not being stiff enough to withstand the side strain when tightening up the nut after adjusting brakes. We believe if these covers were made of steel, it would overcome this trouble. Otherwise, they are a great improvement over the leather covers. The actuating shafts have operated satisfactorily, & the bearings are in good condition. The improved rear brake covers to N. Sch. 2039 have remained in good condition. As previously reported, water enters the drums, but we have had no occasion of any grit becoming lodged in the aperture, & inside of brake drums shews them to be effective in keeping out sludge, etc. We have however come across a slight inconvenience due to the attachment fastened on brake drum. This is due to the brake drums having become slightly worn, which necessitated the adjustment of the brake shoes, after which we find that it is impossible to dismantle brake drum without first releasing the brake shoes. This is caused by the diameter of the attachment remaining constant whilst the diameter of the brake drums has increased. The rear brake drums, as stated above, have become worn & the surface uneven. The linings of rear brakes are fitted with special feredo G.4574 & G.70007. This material appears to be of very poor wearing quality. It has been necessary during the continuation of the run to adjust the brakes frequently. Examination of bedding of the shoes shewed that considerable wear had taken place on the wrapping shoes & on the toes of the non-wrapping shoes. The braking was actually only taking place on the heel portion of the non-wrapping shoes. This is the same condition as we found at the end of 2,500 miles, resulting in very poor rear braking. Concerning our report re front brakes, the squeaking of the rear brakes is identical. Also, it will be necessary to reline these at the end of 10,000 miles. Petrol tank, N. Sch. 2051 & L.O.P. E.74251. The petrol tank generally is in a good condition. The slight leak reported previously has not increased, & is not detrimental to the running of the car. Petrol tank supports are O.K. | ||
